Why only religious beliefs protected?

[Ahriman]

Excluding?

You mean exclude from protections afforded to religious people?

And that's OK because religion has been around a long time but other views are unhealthy?

I guess we will have to agree to disagree as to what is bad for society.

The people who run this world are not risk takers in the slightest. If there is an established system that has seemed to work for a long time, it will be utilized, and its adherents cared for, perhaps for their entire lives. And on the flip side, people who hold more self righteous beliefs, will not be considered as healthy for society.
