Except others believing in God does negatively impact on non believers lives. I live in the UK where we still have Sunday trading laws based on it being a religious day of rest initially. When I was growing up shops weren't allowed to open on a Sunday because of this religious belief even if the owner wasn't religious. Gay marriage has been opposed and held back by religious people who believe it is an abomination according to their beliefs. When the religious keep their beliefs to themselves and out of politics and law I will keep my lack of belief quiet. While religion and it's beliefs are forced on me why shouldn't I voice my opinion?
