How much should I try to avoid controversial topics during rush?

[Soma]

I'm headed to a quite conservative school this fall, and I'm planning on rushing.
I've been very heavily involved with Planned Parenthood throughout high school. I interned there this past summer, at it was sort of just what I spent a lot of my summer doing.
It's not something that defines me. It's a cause I really believe in, but a big part of why I ended up spending so much time there is that I really clicked with some of the employees. I'm in no way a radical, and I think that people could easily get the wrong impression.
But if someone asks what I did this summer.... that's sort of what I did.
And if they ask if I volunteer anywhere or anything... that's basically it.
Someone suggested that I say I volunteered at a clinic, but I was involved more with the political and financial departments then the actual patient center.
I really don't want anyone to think I'm trying to be dishonest, I just don't want to bring something up that I know could offend or alienate people.
