I believe that one's religion should be respected as long as the person keeps his religion to himself.

Once a person begins to introduce his or her religion to public domain, it should be questioned, accessed, analysed, and criticized - and rightly so too.

Like you implied, religion is a form of philosophy that pleads to deity and morals. Every philosophy should be subjected to logical and rationalized practical criticisms - and rightly so too.

That's my opinion.
