So in the absence of religion, there is no racism, no interests and no wars?

You seem to suggest that banning religion would end up wars or human nature.

And yes, noone should force everyone else, but not only om religious stuff. Sometimes there has been non-religious truths to which people are forced and that collides ireemediably with other thinkings.

I am not sure why one philosophical thinking should be better than other just bc it does not contain religion.

In fact, I consider a big part of most religious a compilation of wise advice about human nature. You can believe it or not, take it or not, that is a choice, but when not taken into fanatism I do not think it is harmful.

Again, that is not anreason to force a position to others. But there are a handful of things that are very controversial.
