People who are ilke Grammar Nazis when it comes to the use of fallacies in a argument. Basically these people are usually in the Facebook comments and in Reddit threads. Also Fallacy Nazis are mostly left wing or factcheckers.
I hate fallacy nazis! They think that the facebook comment section is a some sort of a debate center and they're pointing out the fallacies of people.

Nerds like to use this when they procrastinate.
The mathematical fallacy 2 = 1 is a classic one, guess which step is incorrect:

Let x = y.
Multiply by x: x² = xy.
Subtract y²: x² − y² = xy − y².
Factorize: (x − y)(x + y) = y(x − y).
Divide by (x − y): x + y = y
Because x = y, replace all x's with y's: y + y = y
Simplify: 2y = y
Divide by y: 2 = 1

Did you see the incorrect step? Spoiler alert: it's the fifth one; you can't divide by (x − y), as that equals 0 (because x and y are equal), and you can't divide by zero.

When someone in an argument attempts to deny your argument by nitpicking a small mistake, such as a mis-pronunciation or typo. Named after the famous "end him rightly" meme, where a fencing opponent throws their pommel in your face as a distraction.

A subcategory of the common strawman fallacy.

A Redditman Fallacy is when a user pushes an agenda by showing a screenshot of a reddit post. This reddit post is usually atrocious in quality or with terrible takes, in which the user may clown and easily defeat the argument in order to push their agenda.

An example of this is clear in politically motivated twitter accounts using screenshots including but not limited to reddit posts
Very smart individual 1 : Look at this reddit post of <group they disagree with>! And they're calling us <insert buzzword>
Very smart individual 2 : Wow, I agree,

Everyone else : This is literally a Redditman Fallacy
