Nah, porn isn't going to change gay rights, these guys in porn like to act as if what they are doing is important and somewhat examples of "sexual freedom", but they are just selling fantasies. Remember that these people, like any other people exposing themselves online, have online personas, their real sexuality is unknown. When we see people like gay hollywood actors/actresses going for straight relationships, then we have to start worrying, lol. These are the people that are most known to the public, that your neighboors watch on tv and acknowledge that gay people exist.
I'm mostly on this thread for the gossip, some of these actors have great conversations and contradictions on twitter of how they are even fucking a lot of women, but still very, very and only gay, lol.
