It's always good to get on with the faith societies on your campus as it provides a fantastic arena for debate. The attitudes of other societies varies largely from campus to campus and from society to society so a lot of the following information is based purely on personal experience and you will really have to feel your own way. Remember also that the better you know a set of beliefs, the better you'll be equipped to rip them apart.

Christian Union

Chances are your Christian Union will be a really nice bunch of people. They are determined to show everyone else how amazing the Christian lifestyle is, are friendly and always willing to chat. They are also very likely to be up for running joint events, both in terms of debates and socials. Remember that Christian Union groups tend to have hundreds of members. If you want to publicise an event, the CU could be a good way to do it.

Many Christian Union groups will either run, or be linked to in some way, an Alpha Course group. These meetings are perfect for honing debating skills (and shaking the beliefs of a few Christians while you're at it).

Christian Unions are often well funded by local churches and by UCCF - the Universities and Colleges Christian Fellowship.

Muslim Societies

Many campuses also have societies for their Muslim students. Such societies are good for information, particularly in determining whether something you've read on the internet is a widespread belief or not. Generally speaking the Muslims in such societies are not the fundamentalist types. Debates on things like Muslim extremism are also easier to organise when there are 2 points of view. Remember that Muslims believe the Koran to be the literal word of God written by Mohammed. If you can find something wrong with it (and there's plenty wrong with it), that's a big nail in the coffin of any argument.
