I don't know as it's a matter of people becoming thinner skinned.

I think it's more a question of building egotism. 'I have a right to talk about my religion and personal beliefs. If you don't like it, sod off.' seems to be the running mentality.

It used to be that religion and beliefs weren't discussed because it was assumed that it was not a desired topic unless one was first asked, or in a venue that promoted such things. The discussion of belief and religion has spread past those bounds, and is fairly omnipresent, currently.

I'm with Athelind on this one.
