For me, you saying "hey, can I use slurs over there yet? Specifically, ___" is a bit like the dudebros that yell out "Equal rights, equal fights!" as they pretend to punch a woman ... like ... why the fuck did your mind go there immediately ... it's a bit disconcerting.
Had you said something like "Do they still have the hardcoded blocked words, still? I used to laugh whenever someone from England tried to mention cigarettes and it gets [REMOVED]! Haven't seen that in a while though" I don't think you'd have gotten the downvotes.
Just my opinion, others may have had different reasons to dislike your comment.
ETA: Your other comment wasn't showing before. You identify as the word and want to be able to use it and not have it be labeled as hate speech when it's against yourself ... So ... I'll update my "had you said" to "Hey, are they still redacting fag over there? We're trying to take that word back into the community (similar to how queer has largely been taken back) and it's real fucking hard when it's [REMOVED]!" instead.
