Yeah there’s a few people I’ve run into in bars and clubs that think using the f-word is normal. Well it might be normal to you…or them to use it, but it is 100% a slur against homosexuals, whether you intend it that way or not. Maybe it’s ignorance because you’re young, or whatever but it is.
So my advice to you is, when you’re in public, be damn sure if you plan on using that word that you’re surrounded by other bigots where the word is normalized. Had you used it in my presence, you wouldn’t even get the chance to apologize and you’d be eating through a straw for a month or two.
