Do hetero men really need straightdar?

Gawker has already commented on this and the author isn't as asinine as he first seems if you read the whole things, but come on.

"This is the dismal magic of the Straight Sign. It's a way of saying,
"Dude, I'm not gay. I'm not putting the moves on you.". This is the card that inevitably must be thrown on the table to indemnify all future conversation against perceptions of sexual interest."

two problems:

1) "Dude, I'm not gay. I'm not putting the moves on you," suggests that 'I'm gay' = 'I'm trying to put the moves on you.' Not likely. Yes, there are gay men who have trouble talking to other men without plotting to enter their pants, but if you are chatting with one of them at a bar, you already know it and they are already aware that you are talking to them because you want to sleep with one of the women who you will never sleep with unless you get their approval.

2) "...indemnify all future conversation against perceptions of sexual interest." WTF? Can boys who think this talk to girls without thinking about having sex with them? Jeeze man, what do you think is going to happen if another guy is interested in you? It isn't like we are running around trolling straight bars for the first schmuck who will talk to us so we can drag him into an alley and vandalize his pristine he-snatch. If a guy really wants to have sex with another guy, it takes about twenty minutes of keeping your eyes open anywhere in this country to find another man who is more than happy to accomodate you and about as many seconds here in NYC to accomplish the same.

You dorks need to calm down. If the guy you are talking to at a straight bar does turn out to be gay, the fact that he is at a straight bar means he probably isn't on the prowl. Do you go to gay bars to pick up chicks?
