This is one of my biggest pet peeves. Yes, there are women out there who may be playing at being gay, who aren't really bisexual. But who the hell are we to judge that?! No one.
I've been told to 'pick a side' more times than I care to count. I've been told I can't really be interested in women because I'm married to a man.
None of that is valid. I love women, romantically, sexually, and otherwise.
To me, that's no different than telling a gay person they can just change who they are, and that's just bullshit.
