What to do with the returnees?

“You're an atheist, nothing is sacred to you.” Human dignity is for me, that is why I am not only Atheist (which means not believing in an In/out Space Creator, no more) but as well anti-religions, as I hate to see people kneeling in front of whatever for whatever reason.
I believed in few things, e.g., Justice (concept), freedom (concept) and reason (even if often disappointed).

If people want to believe in something why bother them as long as it doesn't affect you. And only that long, no further. But why harm what doesn't harm you, and smash it once it does.
