Noahidism is not a variant of Judaism. There was a time before Judaism existed and, according to both of our worldviews, people still had a belief in a single, all-powerful creator G-d. That is, G-d, A-lah, whatever one calls Him. My faith calls these people Noahides. If you want to argue that Noahidism isn't a religion, you would be totally right. It is not a religion, it is a belief in G-d the same way one believes in the sky or the moon; just a part of one's life. By virtue of that fact that Judaism exists - in any form - Noahidism too must exist, as there are non-Jewish people who believe in G-d, the same G-d of the Jews, but are not Jews. There is no requirement to convert to Judaism, but these people can serve the Creator and worship Him all the same. These people are Noahides.
Still, the fact that you basically tried to invalidate my faith was pretty nasty, but it's OK because you're wrong.
How? What insecurity? Stop trying to invalidate my faith. Would you like to know what? I hate the Baha'i faith. I hate it because it's a faith that tries to take figures from every religion known to man and incorporate them into its narrative and say they all taught the same thing, from Krishna to Abraham to The Buddha. It also thinks that one day it will dominate the world. It's a mess of world faiths put in a blender and turned into an unrecognisable mush. No other faith is so arrogant as to take any and every religious figure and claim them for it's own. Your faith is insane.
