Ah yes, I'll take the words of this straight man who's never had to deal with having slurs yelled at him

How the hell does that remove any credibility to his point? It doesn't matter what his past experience was or if he understood how people targeted by labels felt, what matters is his point that a word alone is entirely neutral and the people behind the word give it power, just like a firearm is either protective or life threatening depending on what hand it's on and where it's aiming at, This comic did not have the intention of degrading any majority/minority because the context of the word as an insult depends on who it's aimed at, in this case it's directed to Nick from which from the sources of the directors and canon material, his sexuality is entirely neutral meaning he belongs to neither party, plus the origins of faggot are not just a slur for homosexuality, in the UK it means either meatballs, cigarettes, and or bundle of sticks, the US version of faggot is entirely slang and depends on what party is using it, just because it's being used as an insult doesn't mean it's not any of the 3 aforementioned objects, any of those 3 objects can be insults just take a look at asshole,prick, and cunt, they are all simple nouns just charged with negativity, but my point is that a word like faggot only means it's base origin meanings until it's confirmed to be a used as a slur, in this case since Nick is not homosexual(from what is canon) the insult could easily mean something else entirely
