There are a lot of ways to be an anti-Christ according to the Bible but the Bible is bullshit. An anti Christ is someone who is a liar who tries to make you think that wrong is right. An anti-Christ is the antithesis of the general morals and teaching outlined in most Christian doctrines. People do that by talking the talk bit never actually walking the walk. The Bible belt is ground zero for the anti-Christ.
Trumpism is the anti-Christ. Trump supporter are the anti-Christ.
