Writer's Block: Agree to disagree
No. To end a friendship just because you don't agree over some issue as trivial as that is plain absurd - at least for me. But I once had a friend who ended our friendship over something almost the same as that. I mean, she told me we couldn't be friends anymore because I'm from a different religion, and that she wasn't allowed to build a close relationship with somebody who wasn't a part of them. But that was ages ago. I got over it now.
