The religion of Judaism, whatever branch, can determine for themselves who they want to accept as "Jewish" - whether Indian or African CONVERTS to the religion of Judaism. No problem. Your religion. Your converts - real or imagined.
That's when the religion of Judaism crosses the line and must be opposed: when it attempts to steal our Israelite identity, the Hebrew roots of the West, and transfer them to Gentiles who want to move on up to Westernized Israel. Such identity theft will continue to be exposed and condemned, as it should be. Have your converts, just don't pretend they're ethnic Israelites because they're not. If they are, then you're not! It's that simple to objective folks.
