Well this is a topic that has troubled me especially lately I didn't notice any other threads on this but I'm probably wrong so anyway let me know if there is ^^.
One issue I have had on Diaper related gay sites and in the gay male community myself is discrimination against many different groups is the hatred and disliking of anyone who is bi/gender indifferent/pan or what ever thing you want to use for that. I have had many arguments over this with people and I'm sort or sick of people telling me I'm just indecisive :P because I really don't care about people's plumbing.
One setting I put forward to some people was if a gay male was dating a bi similar orientation guy and that person cheated with them with another male they where upset but if they cheated with them with a girl from what I experienced most guys have said that's 10 times worse. This is just one scenario.
I just think its stupid for a group fighting for right and acceptance to be so discriminatory, I do understand that the world doesn't function as a utpoia either but argh i dunno opinions ?
