To Theists: Why are most of your questions here directed towards atheists?

I understand that atheists are likely to group all religions together, and likely to debate Christians because they are the largest religion in the english speaking world. Why, though, do Christians not debate Jews, Jews debate Muslims, nor Muslims debate Buddhists (not a theistic religion, I know, but the example is valid, I think) more often?

Surely their views are as alien or bothersome as those of atheists. After all, they do not beleive what you beleive. The banner says debate ALL the religions; why the (mostly) two way street?
