is it wrong.....?

Yes, but only if you feel bad afterwards or annoyed.

You shouldn't really be telling your parents anything if they will mock you, also.

Now I don't believe in Atheism, and agree with trying to witness, but if your parents are truly mocking you... no. That just isn't right. Jesus didn't mock people, did he?

But by the way- if what I think nondenomimational means is what you think nondenominational means, there is a LOT of difference.

I think it is wrong for parents to mock their child for ANY reason. It may be that you'll just have to develop a thicker skin for now. They won't always be there, so try to make the best of what you've got. Stand up for yourself, but be respectful (even if they aren't) and don't push it to the point of making homelife unbearable. It takes two to argue. Good luck.

It is not right for anyone to mock anyone else because of his/her beliefs. It's not cool to make fun of people who are religious, either. YOU be the better person and just ignore them as best you can.

Yes, your parents are supposed to support you.

Yes its wrong. They are being jerks.

Oh, so atheism is a religion?

your parents are morons
