“I hate (let’s say, the color blue) because my toxic ex likes it and therefore because they’re a bad person, everyone who likes blue is a bad person and should die!”
“I hate (let’s say, the color blue) because my toxic ex likes it and therefore because they’re a bad person, everyone who likes blue is a bad person and should die!”
That’s an argument ad hominem. That bad person endorses this thing, therefore that thing must be bad.
“Ad Hominem” just means you are insulting the person rather than addressing their argument. Like, calling someone stupid, instead of explaining why what they’re saying is stupid.
