Speaking as a non-Christian, I even find that there is still stuff worth reading in both Jewish and Christian scripture. I can't speak for the Quran because I haven't read it, but in the rest of the Abrahamic scripture and the commentaries on that scripture there is some seriously compelling metaphysical and philosophical stuff going on there. There's a fair amount of truth in both the Jewish and Christian bibles. The trinity isn't even that far-fetched of a theological concept, in my opinion. It's certainly easier to understand than Kabbalah, which I also don't think is very out there.
I don't begrudge anyone for being a Christian or a Jew, or a Muslim for that matter, even if I know a fraction about Islam compared to what I know of Judaism and Christianity. Or anyone of any religion. Most religions are fundamentally describing the same thing.
I think you should extend a little bit of good faith to people of all religious backgrounds. All flavors of Abrahamism, Hinduism, Buddhism, Sikhism, European paganism—there are little bits of truth here and there in each and every one of those traditions. I don't think it does you any good to look down on people that choose to follow a specific faith, least of all yourself.
