I belive in evolution but my religious friends say to me that my gramps is monkey they don't even know single thing about evolution what to do with them
Just say no, they've got it all wrong. I'm actually a really distant cousin of the chimpanzee down at the zoo and our DNA proves it.
That would depend on how ingrained their beliefs are. I live in a mostly openly atheist community. Many do not.
I have friends from india and Sri Lanka who are extremely religious and others of Indian descent who retain strong religious ties. Sometimes it is becessary to keep our thought quiet. You will be the best judge of what reactions you will get. Good luck.
Ifyou feel disrespected make some new friends. They are ignorant.
I have a couple of T-Shirts which read "Fine, I evolved, You didn't."
