I don't know what the number would be. Certainly a lot.But I can promise you there are hundreds of thousands, if not millions of people that want you dead just because you're not a Muslim...and an American.
The majority Muslims do like Americans though. The vast majority of the ones that don't live in parts of Pakistan, Afghanistan, North Africa, and the Middle East. The areas where most Muslims live overall have a really positive outlook on Americans.
We should stop arming countries that support terrorism (actually I can't see protecting most of the Middle East countries), though this probably doesn't belong on the main forum.
