Well, I don't think that Christians' worship of God is connected with Eurpoean paganism at all, except to try to convert them from it. Thus, I find the allusion to such to be at least mildly offensive, even though I doubt that you seriously intend it that way.
However, I suspect that in the same way that I am offended at having a faith that is in fact rooted in the worship of Yahweh to be equated with paganism, that you may have felt the same with my own self references by which I ascribed Islam to my worship simply because I understand myself to be seeking to live a life of submission to God, as I'm sure it doesn't really fit your definition. Since you probably see that as shirk, I suspect you might be offended, even though I do not mean it that way. But by my way of thinking if Jesus taught Islam, then I am following it because I am attempting to follow what I understand to have been his teachings. We just disagree with regard to what we believe it was that Jesus taught.
