Ippy: One thing for a start would be to stop giving undue prominence to religious ideas, such as having a university subject headed as theology, when theology should come under the general heading of philosophy.
You've said that umpteen times on this thread, ippy, we all get that is what you mean! It may well pan out that way too in the near future.
I get what you mean about religious indoctrination too, subtle and not so subtle, and your hatred for it comes across clearly. However there is plenty of subtle and not so subtle indoctrination of other ideas which we all come across every day, we only have to put on the TV to experience that and it is far more prevalent than god-bothering.
We are not going to be able to ban personal opinion or stop people expressing their opinions to others. Whether it be obsession with religion (for or against), politics, money, cosmetic surgery, criminology, sport or whatever. Many of those subjects have dangers and are studied at university in one form or another. We can't ban things just because they make us see red or because we fear our children might take them up and come to harm.
As for my "RC lot", I've said several times that I am not a practicing Catholic and haven't been so for many a long year.
