In my opinion sexual desire for the most part has nothing to do with love. Love doesn't create sexual arousal it creates deeper bonds that go way beyond lust.
I accept people who are drug takers, love tattoos into group sex etc etc doesn't mean i have to associate with such people.
I have a close bisexual female friend, she knows my stance and is accepting of it and in many ways agrees, she is totally against the rainbow movement and what it stands for presently.
I wouldn't associate or have friendships with gay or bisexual men though(not out of hatred i just don't feel comfortable around their personality types) but i would support or defend anyone in need regardless of their sexuality and i treat all humans with equal respect.
