Haec Est Pseudoscientia Fallacy
A fallacy where someone dismisses arguments by labeling them "pseudoscience." The label functions as dismissal: if it's pseudoscience, it's not worth engaging. The fallacy lies in treating the label as refutation, ignoring that the boundary between science and pseudoscience is contested and that labeling something doesn't prove it wrong. It's argument from authority dressed as methodological critique—using "pseudoscience" as a magic word that makes arguments disappear.
"I presented evidence for alternative healing practices. Response: 'That's just pseudoscience.' That's Haec Est Pseudoscientia Fallacy—using the label as a dismissal, not engaging the evidence. Maybe it's pseudoscience; maybe it's legitimate but marginal. The label doesn't settle it. Calling it pseudoscience avoids looking at what I actually presented."

Relativista Es Fallacy
A fallacy where someone dismisses all arguments of a person by labeling them a "relativist." The label functions as a dismissal: relativism is assumed obviously false, so if you're a relativist, nothing you say matters. The fallacy lies in treating the label as refutation, ignoring that there are sophisticated forms of relativism and that labeling someone doesn't engage their arguments. It's a conversation-ender dressed as philosophical critique.
"I suggested that different cultures might have different valid moral frameworks. Response: 'Oh, you're a relativist—debate over.' That's Relativista Es Fallacy—using the label as a dismissal, not engaging the position. Moral relativism is a serious view with defenders; calling it names doesn't refute it. The label ends conversation; argument would start it."

Postmodernista Es Fallacy
A fallacy where someone dismisses all arguments of a person by labeling them a "postmodernist." The label functions as a dismissal: if you're postmodernist, your arguments are automatically confused, relativist, or nihilistic. The fallacy lies in treating the label as refutation, ignoring that postmodernism is a diverse tradition with serious thinkers and that labeling someone doesn't engage their actual claims. It's intellectual dismissal by category association.
"I mentioned that knowledge might be socially constructed. Response: 'Oh, you're one of those postmodernists.' That's Postmodernista Es Fallacy—using the label to dismiss, not engaging the claim. Social construction of knowledge is a serious position; calling it 'postmodernist' doesn't refute it. It just shows you'd rather name-call than think."

Conspiratista Es Fallacy
A fallacy where someone dismisses all arguments of a person by labeling them a "conspiracy theorist." The label functions as a conversation-ender: if you're a conspiracy theorist, nothing you say needs to be heard. The fallacy lies in treating the label as refutation, ignoring that some conspiracy theories have proven true and that the label is often used to dismiss legitimate inquiry. It's ad hominem by association—using the stigma of "conspiracy theorist" to avoid engagement.
"I raised questions about government transparency and corporate influence. Response: 'Oh, you're one of those conspiracy theorists.' That's Conspiratista Es Fallacy—using the label to dismiss, not engaging a single point. Some questions about power are legitimate; the label avoids them. Calling me a conspiracy theorist doesn't make my questions disappear."

Radicalis Es Fallacy
A fallacy where someone dismisses all arguments of a person by labeling them "radical," "extremist," or "fringe." The label functions as a dismissal: if you're radical, nothing you say needs engagement. The fallacy lies in treating the label as refutation—as if calling someone radical proves their arguments wrong. But radical doesn't mean false; it means outside the mainstream. The mainstream can be wrong; radicals can be right. The fallacy is particularly insidious because it uses social position as epistemic judgment—confusing marginality with falsity.
"I presented a critique of economic inequality. Response: 'That's just radical leftist nonsense.' That's Radicalis Es Fallacy—dismissing by label, not by argument. Maybe it's radical; maybe it's right. The label doesn't settle it. Calling me radical avoids engaging what I actually said. It's ad hominem by political category."

Argumentum ad Te et Verbum
A compound fallacy combining Argumentum ad Te and Argumentum ad Verbum: claiming that someone is proving the opposing point by their word choice. "You are proving the point of the post by trivializing the word X" is the classic form. The move claims that the way someone uses language demonstrates the truth of what they're opposing—a double evasion that avoids content by focusing on the relationship between word choice and argumentative position. It's meta, it's clever, and it's completely unresponsive to substance.
"I used the term 'conspiracy theory' carefully in a critique. Response: 'See? You're using that term exactly how the post said people would—you're proving its point!' That's Argumentum ad Te et Verbum—using my word choice and my position to dismiss my argument without engaging it. My word choice becomes evidence against me, my response becomes proof of their point. It's a rhetorical hall of mirrors with no exit."

Argumentum ad Verbum
A fallacy where the focus shifts to the words used in an argument rather than the argument's content. "You are trivializing the word X" becomes a way of dismissing claims without engaging them. The move criticizes word choice, terminology, or phrasing—often legitimately, but fallaciously when the word critique substitutes for content engagement. Words matter, but when "you're using the wrong term" becomes the whole response, the substance gets lost. Argumentum ad Verbum is particularly common in online debates where semantic nitpicking replaces substantive discussion.
"I described an experience as 'traumatic.' Response: 'You're trivializing real trauma by using that word casually.' That's Argumentum ad Verbum—focusing on my word choice, not my experience. Maybe the word was imperfect; maybe not. Either way, my point about what I experienced remains unaddressed. Words matter, but using them as a shield against engagement is fallacy."
