If it was baseless, then I wouldn't be bringing it up.
I can't count how many times me or a friend has said "hi" to a girl at a bar/club only to be flat out ignored and even treated hostilely and told to "fuck off" (or something of that vein). On the other hand, I've never witnessed a female friend of mine being treated like that for saying hi to a stranger.
I realize that anecdotes are just anecdotes. But I'm sure you can find YouTube videos of what I'm talking about.
