Refers to someone who gives "ideas" about how things should have been done differently, or needs to be done in a better way, but has neither the ability nor the knowledge that required to deal with the case, and has never been in a similar scenario and never experienced in the like. Resembles the proverb: "After the ship has sunk everyone knows how she might have been saved".

Not to be confused with an Armchair Activist or Armchair Warrior, an Armchair Crusader is a person who would essentially die for another person unrelated to their life. Most often found in cult-of-personalities surrounding larger names, these people would blindly talk up about, defend, and proclaim falsehoods of counter-evidence towards a person's character, regardless of the relationship between the person and the crusader.
In essence, they would die for a person who doesn't even know they exist.
Any large YouTuber has a ton of these. Try insulting their character and see how many of them jump to his/her unneeded rescue!
Celebrities have many, or even just famed creators of great works (movies, video games, etc.)

a person who only cares about biology when they wish to invalidate trans people … likely never engaged in biology class beyond that cheat sheet they made for their ninth grade final exam.
“These anti-trans bills are the latest wet dream of armchair biologists who love saying, ‘trans women are men’. Yes, we get it - you think we’re hot, and that scares you.”

Someone who is fascinated about touching people's feet, but not as a fetish. They usually have beginner-level knowledge on the anatomy of the human foot and can also give great foot massages.
My sister's boyfriend is kind of a creep about her feet, like an armchair podiatrist.
