"You don't see Christians, Jews, or Buddhists trying to proselytize by putting down other religions and mocking their traditions"
Do you mean something like this:
Here Muslims Hijack Jesus:
Here Chrisians (presumably, since the organization's chairman is Council Nedd, an Episcopal Bishop) Hijack The American Flag and explicitly ask why Atheist Hate America:
Sure, religions do that.
Well, First, Muslims do consider Jesus a prophet of their religion, so that sign is factual of their beliefs. However, I believe are clearly trying to incite/annoy Christians with that sign.
As for the second sign, this country was founded on Judeo-Christians beliefs. Atheists in this country consistently attack people with Judeo-Christians beliefs. I’d say atheists do hate America.
Also, didn’t the exit polls showing atheists overwhelmingly voting for Obama? Yup, they hate America.
