I love it when I hear of others coming out
It should not be news worthy
And I wouldn't say that sluts don't affect the general perception of straight women. How many men think all women are sluts? Enough to have stories in the media about how women are mistreated or have all that stupidity about the club dating culture. You go to the club, pick up a chick, bang her and leave and repeat the process periodically. It's why clubs exist to begin with because shallow people with no moral or respect standards who don't care about engaging in risky sexual behavior love to go there. It's why "the club" changed it's meaning from the victorian era where it was a place of intellectual conversation and model behavior to a pathetic display of the most base of human interactions. Again, it's just enough to have this sort of thing take place. It's not prevalent.. .or maybe it is, I don't know how we can test for this... but it exists.
So your argument falls flat on its ass. And it's not like you need to think about it for long to understand why it is a fail argument. The reason why I posted the pictures of men is because when I googled "homosexual" that's what popped up among the first page of images.
EDIT: how do you know those women in your pictures are straight?

I think that not only is the public in general far too interested in what people do in bed, the celebrities are only too happy to tell everyone what's going on. Sexual orientation shouldn't matter, it's nobody's business what two consenting adults do and it shouldn't be news. People who announce it ought to be reviled as low-class.
