It doesn't matter what you do. I have engaged in debates against Islam more times than I can count and I've been called everything under the sun. When I talk badly about Christianity it's silent. You haven't been here long enough.

I have though...(been here long enough)
Take this opinion for what it's worth, but I've seen plenty of push-back from Christians on (for example) atheists suggesting that all Christians are irrational or illogical.
Never worries me, since half the time I agree (if wince at the irony in complaining that 'atheists' are overstating things about 'Christians', as if either group is homogeneous).
At the risk of making the sort of broad-sweeping statement I am arguing against here, saying anything about 'Islam' probably guarantees you are wrong (or at least, over-generalising). Same with Christianity. Same with atheism.
And simple answers for complex issues are commonly unhelpful.
Conservative Christians who claim Christianity is the one true religion are just as wrong as anyone else claiming their religion is the 'one true religion', to my mind. But that claim doesn't worry me. I would think all true believers (be they conservative or liberal in nature) would see their religion as true, and many would see them as the one true religion. The difference is more around what they see as the implication of that statement.
1) I follow the one true religion, and I hope through my compassion and good example I can show people that God is love.
2) I follow the one true religion, and non-believers are subhumans. I am the tool of God's punishment!
One worries me, one doesn't.
