I'm not saying that people are evil (at least not in this thread), I'm just saying that no person ever knows what is in another person's heart. Or what their motivations might be. Could be they like you and want to spare your feelings, or that they are just humoring you or outright lying to you (OK, those might be evil), or that they are just not up to a fight or argument, or they just don't care and say the easy thing to get out of it, or that they don't want to take the heat for 'having the wrong opinion or idea' (and there is a lot of that, I'm sure - despite the notion that the arts and entertainment are so very liberal - that there are just as many racists in Hollywood as in any other population, it's just that they know if they said that stuff out loud they'd be out of a job, so they don't).
So that...there are just some things you don't ever get to know and you have to find a way to be content and at peace with not knowing.
