Advice please ...

[Magic.]

OK so I'm not willing to go into what happened, I've only told very few people and that was hard enough, and I don't think posting details here will help.

Basically my dilemma is I have a course at uni called Sexuality, Gender and Society, which is for my psych course and is heaps interesting. However there is a subject that will arise in lectures and the discussion tutorials which I don't know if I can handle. Basically it's the view of the llaw on abuse etc, and whether it's evolutionary / some men can't help it etc.

Now I can skip the lectures as they aren't compulsory, but our tutorials we have to attend for a large part of our overall grade. And it's a much more in depth discussion with 20-25 people. I know that most people will shoot down the arguement because it's absolute cr*p, but I still don't think I can be there.

How can I approach my tutor and excuse myself without having to explain it to him? I spoke to my best friend who knows and he thinks they'll say it's my fault for not looking more into the course first - but these details weren't available until after I enrolled. He wanted to phone the uni and ask them about it and offered to talk to my tutor, but I think I have to deal with this myself, as I can't have him fight all my battles ... I just don't know what to say without saying too much / crying like an idiot. Help?
