What is your RLS? If your RLS is something based upon a story such as Persepolis by Marjane Satrapi, then you could talk about setting/context of it. Though, you may have to be a bit careful about it as it could be considered a 'touchy' topic. You could state, but always give proper evidence that's been verified.
The thing about claims is that you have to give your own opinion about it. As of now, you've given a very vague information about your TOK presentation. So its either best that you 'claim' as "Yes, religion does influence the education system in a society to a certain extent" and your 'counterclaim' would be just the opposite of it.
