I don't really care. The lines between different orientations are heavily blurred. In some cultures its the norm for people, no matter what gender, to kiss each other on the cheek. In ancient Greek and Roman culture, it was the norm for pretty much everybody to have sex with both men and women. They didn't even have a word for gay or gay sex, it was just sex.
People's sexuality isn't just confined to one orientation label, and it's very much influenced by their environment in my view. I call myself bisexual, but really only because that's easier then explaining the complicated details of my sexuality (I guess pansexual would make more sense). There are certain forms of affection, intimacy, sex and romance that the idea of appeal to me for both genders, people, situations, ect. It all depends. So I've basically stopped caring about where the lines are, because there is no objective line between different orientations and intimacy and affection. It's a subjective thing, everybody has their own desires, limitations and tastes.

Holding hands is just plain gay.
Exactly. If two men hold hands with each other, then that must mean they would also like to have sex with and enter a relationship with people of the same gender.
There is no line, draw your own.
