Thanks for the warning. Fortunately you can choose your friends, but unfortunate that it ended over this. Several angles you could take here. If they're really "best friends" you should be able to say what you want, damn the consequences. Telling you the hard truth is what friends are for. Especially if you're going to end up getting cut off. Speak now or forever hold your peace. Actually, it sounds like you did.

I'm not too worried about the "gay agenda" though. A third of the girls in my middle school were "lesbian" and they aren't now. It's just a phase. Better that then a thinking she's a tranny, and doing something she can't take back.
