Got called a faggot today at work.

I've been venting about this to a few other people today, but I figured it would be good to come here too.I was expecting a lot better from a big, liberal city in Canada, but I guess I was wrong. I work at a repair shop within a larger department store. I don't want to reveal too many details but I was working alone today when this younger guy about my age came in with something of his to fix. I took a look at the damage, told him I probably might have to send it in to someone else, but I'd give it my best shot. Well, I couldn't fix it, so I handed it back to him. But then he started blaming me for the damage, claiming that I "fucked it up." He said, "Is there anything you can fucking do about this or should I go fucking complain?"I told him he could go ahead and complain, but then he said, "Fucking faggot," and stormed off, grabbing the clock that was sitting on the table and throwing it at me while he had his back turned. I was standing way to the side, so I wasn't in his line of fire, but it bounced off the wall and landed on the floor next to the till.I had lived twenty-two years on this planet as a gay man without having been called that slur before, so it was a little difficult for me to take. I think I was still in shock because I continued to serve customers for another ten minutes before it occurred to me to call my boss about this incident, or let security know. They're reviewing the footage now and have issued a ban from the store for this asswipe.The weird part was how calm and passive I was during this whole exchange. He called me a faggot just before walking away, and I didn't think about calling him out on it or asking, "What did you just call me?" until long after he was gone. I guess I didn't think i was worth the fight. In retrospect, I kind of wish he had physically attacked me as well, so that I could have the satisfaction of watching security tear him off of me and fuck his shit up after I go feral on him. But should I have said something?On my way home, I heard Tommy Heleringer's beautiful voice from the Season One finale of The Outs in my head:I want you to look the next stranger who calls you a faggot in the eye and tell him that he's a bottom-feeding piece of shit, and that as a faggot, you know how to do a lot of things to a man's ass, one of which is kicking, and that he should sleep with his third eye open, because you're comin' for him in his worst nightmare ...Does anyone else regret not standing up for themselves? I feel like I should have done more than I did in that situation.
