>>3 You're not a bad influence but they think you are. They're afraid their little girl is going to go gay if she hangs around with you. That's complete bullshit, of course, but that's how their little minds have to justify it.
There's nothing wrong with talking to her. Keep doing so.
>>2's advice would only apply if she was still in her mandatory schooling and such, but she's in college. It's her decision now.
And how on earth are her parents going to "take her out" of college without her permission when she has a scholarship to pay for it? I don't see how that's legally possible in any way even if she's underage.
