It is wishful thinking to blindly believe all religions are "good and great". Religion has been one of the biggest causes of deaths the world over in history. If one wants to prove religion is "good and great", it has to be done by stating facts; just saying so wouldn't make them. In my opinion, religions are man-made set of rules when mankind were nomadic (in a way they are "non-stationary" countries). Their creators just quoted God for authority over their people. Religions can be evil.
The bottomline, it is all well to turn a blind eye to evil interpretations of religion (and those who do that are of no danger to anybody but can be in danger themselves), but there will always be people who interpret religions violently and kill people. This must be recognized.
