It's as simple as that. Yes, I know that the rules of English say that a proper name should be capitalized, but Jewish Law is much more important to me than any other law. And Jewish Law says it is forbidden to show honor to a false god. All other gods are false. It doesn't matter if Christians feel that he is the real G-d.
Christians are wrong.
Jewish Law says that jesus is not G-d. Therefore, by Jewish Law, I cannot give respect to jesus. Hindus believe that their gods are real. That doesn't change Jewish Law. Christians believe their god is the same as the Jewish G-d.
