Really?
The difference between Islam and Christianity amounts to roughly 10% of the total content. Barely more than the difference between Baptists and Presbyterians. Same god, same general tone to the "Books". Including the nasty bits and the extremist nutjobs in both camps who ruin everybodys reputation.
Around 1/3 of our Australian modern and western society are actively christian, and another good sized chunk kind of but not really active.
I've heard school children sing "Allah Allah is God, Mohammed is his profit." Know what the second verse is? Allah Allah is God and Jesus is his prophet." There is jack shit difference between "us" and "them".
