Sorry, I don't do argumentum ad Youtubem. (Didn't watch it.)
And I'm asking about why atheist "non-stamp collectors" proselytize.
I already know why evangelists do it.
He used it as an example. You don't need to watch it to know what he is talking about.
Theists vote. Their vote impacts other peoples lives. Therefore, we all have a reason to question their reasoning if it's based on unverifiable claims.
Would you want a Muslim voting for policies that would impact your children's education, you freedoms? Maybe, maybe not, right?
If you disagree with a vote that forces women to wear head-coverings, wouldn't you speak up - and attack their fundamental belief that God wants women to wear head-coverings?
After all, if they claim it is a command from God, it's not enough to say "Hey, we live in a pluralistic society. We have to accept different views", because the Muslim would say "but it's not me saying it, it's God."
Now you have to PROVE he is wrong. How could you even begin? Even WLC doesn't claim to prove Christianity, he only says his arguments make it rational to believe in. (If I only presented positive arguments for Islam, I too could claim it is rational to believe).
Learn to accept: Your beliefs (in God) impact other people.
