I'm not sure exactly who you guys are talking about, but what's wrong with telling a female she looks good? Why's it so horrible to tell a female she looks good through the internet when it's perfectly fine to do it in person? I tell ladies that they look good in person all the time, but that doesn't mean I'm trying to get in their pants.
I don't see anybody going overboard tryna get phone numbers or stalking anybody, so I don't see the problem. Maybe you guys are taking it a little too seriously.
I'm not going to come in here and tell other men that they're gorgeous for obvious reasons.
