1. This feels like frustration at proselytization competition. Bringing people into the House of Peace sort of gets in the way of piling the whole world into the van and driving them to the City of God, huh?
2. How acceptable, in Christianity, is it to criticize Christ's practices? Maybe this is a problem with theocracies more than specific religions?
3. This is a nice appeal to authority. I suppose, on matters of religion, we should all just step aside and let you preach.
4..Well, I haven't even taken Comparative Religions 101, but I think I know enough of history over the past two thousand years (not to mention the current moment) to say it's hard for me to buy that Christianity has sufficient moral high-ground to look down on Islam in judgment.
I feel like there's something you always say about minding your own house first ...
