You keep sounding like a bigot to those of us who are gay. Or have gay loved ones and friends.Is that "PC"? -- not liking something that describes us or our loved ones in a pejorative way? OK, then I'm "PC." So keep using the term and keep sounding like a bigot. Heck, maybe you are a bigot. I don't know, but your continued use of gay as an insult makes you sound like it. That's your problem.
Find a better word and you'll sound less bigotty. EDIT: I just went through 20 pages on that site you linked to and didn't see any guy in a business suit, let alone a casual sports jacket. W T F are you talking about?
"Full suit"? Stop with the straw man arguments. Has anyone here said undergrads should walk around in full suits? Second being worried about "looking gay" is kind of lame, and maybe a little bigoted. I know you're a kid, but grow up. And also ask yourself, if anyone is ribbing you about looking gay, what kind of person are they? And also are they male or female? You need to stop taking your own insecurities and imagining other people are projecting them onto...
And that's a problem? If you want to look like everyone else, and they're all slobs, go ahead. I'd rather stand out. Me, I don't believe in going over the top - a full suit and tie when everyone else is in hoodies is not good. But a patterned dress shirt or OCBD or button-front sport shirt, casual blazer and chinos (or dark jeans) plus, say, loafers is not over-the-top.
