Mormonism, Jehovah Witness, and other sect aren't Christians because they deny Christian essential doctrines.
While they may use the same terminology like... "we believe in Jesus too" or "we do believe in God also", or " oh yeah, we believe we go to heaven through Jesus Christ" etc.. they all have heretical views and teachings even the most basic and Christian doctrines.
You guys don't diss xwmkab, kevcai, dabqhuas because you guys took everything to be "true" without questioning. lol.
At least in Christianity, we have the basis where we can correct, reproof, teach, refute, know what's right from wrong.
You guys dont do any of that becuase there arent a basis to know what is right or what is wrong. You guys follow blindly at everything.
