why is "no true Scotsman" even a fallacy?

[MysteriousWeeb420]

when person A says no Scotsman puts sugar on their porridge they clearly don't mean that it's physically impossible for a Scottish person to do that - it's just their way of revealing their personal intepretation of the word "Scotsman" and what it connnotes

legit a fake fallacy along with whataboutism

for the same reason appeal to nature is a fallacy

because it can be and someone decieded it to be  one

[Malleus Maleficarum]

it's not a fallacy because what constitutes a "true scotsman" is completely arbitrary/practically a joke

[Altruist]

not sure if serious

Because people use the fallacy to double-down on promoting absolute nonsense. Some people's brains don't work very well, which leads them to think that 'no true Scotsman' is a valid/objective argument (rather than being a fallacy – which it blatantly is), which obviously isn't going to end well in a formal debate.

all "fallacies" are this

appeal to authority: don't care and you're gonna lose this buddy

strawman: this is what i think of you

ad hominem: obviously wrong and i don't like you
