Where's the sexism in my comment? I'm not assuming that straight women are doing all the cock-sucking, nor am I neglecting the existence of gay men, lesbians, bisexual folks of all stripes, asexual people or other people who just plain don't suck cock. I'm just assuming, to a first approximation, that their contributions toward aggregate cock-sucking cancel out. If roughly half of the world has penises, then some half, and not necessarily the _other_ half, of the world is sucking them.
I'm not trying to be snide, I just suspect you're assuming a reading of my comment that I don't endorse. Plenty of people besides straight women suck cock, and the world is better for it.
I'm merely pointing out that the term "cocksucker", when used as a term of derogation, is actually pretty unsavory.
While it's unclear to me whether it's ever off-topic to point out problematic slurs (would you think similarly if the OP had written "they got rid of a faggot..."?), I guess this exchange signals a mutual agreement between myself and the modal HN user about whether we want to interact.
