Time was when my Irish ancestors were worshiping trees. I do wonder about them. Maybe you don't. That's OK, but I do think that we sit on our pedestals with the advantage of having Bibles, and the ability to read them and we sit in judgment of those who have not had the advantages we have had and we tell God what to do.
I don't think it makes you intolerant. I think what it makes you is a God boxer. I mean what you have stated is what I believe, but I also know that I am not God. So if God decides that he wants these nonbelievers then He will have them.
This sort of a statement, in fact, reveals you to be a nonbeliever yourself, a heinous infidel, because you are denying the testimony of the holy scriptures which quite clearly say that there is no salvation outside of Jesus Christ, and denies salvation without faith:
Joh_3:18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
Rom_10:14 How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
