OP - this is kind of off-center of the topic of your post, but I wanted to point out that volunteering and doing AIDS research in NO WAY outs you or casts you in an unusual light. (Now the gay hockey league on the other hand...)
As for your dilemma: I think you have a multitude of opinions on this issue (some more well-thought out and expressed than others) so mine will likely just be one more in the sea. But here it is anyways:
1) I think as someone said a while back - this is a homerun or strike-out scenario by using this in the PS. You must be a good enough writer to "sell" this in the PS or else it could come across quite poorly. I think you should write a draft of this, see how you feel about it, and then solicit some help (from your advisor who has looked at your previous PS).
2) While I think most of his/her advice has been a bit off on this thread, flip26 brings up an excellent point - many schools have 2ndary questions that ask something along the lines of "have you ever faced significant discrimination or adversity in your life and how has it affected you?" - this topic would be a perfect thing to discuss in that section if you don't feel comfortable including it in the PS
3)
Someone brought it up and I think it's important to highlight again - don't make the mistake of coming across as anti-religion. Highlight your parents' intolerance, but don't "blame it" on their being baptist. That would be a double-whammy of alienation in your PS (i.e. your being gay might alienate intolerant christians; an anti-religion bias would alienate even the tolerant ones)[/QUOTE]
I am sick of walking on egg shells so I don't have to "offend" some pious Christian. And, his parents probably kicked him out because they believe homosexuality is a sin- this belief most likely comes directly from their religion. So yes, their religion most likely had everything to do with it. Quite frankly, why should people care about alienating intolerant Christians? As if their intolerance is acceptable? The OP's personal statement won't have an "anti-religion bias" just because he mentions that his parents kicked him out because of their beliefs on homosexuality. What about religious abuse?

And for the record, I have nothing against religion. But, people shouldn't use it to cause emotional, psychological, or physical harm. And, they shouldn't impose those beliefs on anyone else.
