The dudes concerts look like satanic rituals,

Which ones?

he referred to himself as yeezus

Yeah and I used to think we need an all atheist government. People change.

he has been involved with a lot of unsavory characters and unsavory things.

Well yeah he works in the music and Fashion industry. You can't really get high up in those careers without working with some unsavory people. It's unfortunate that the left has force themselves to be the figurehead of expression.

Also the Bible says there are many antichrists not just one (obviously there is a main one eventually but it makes it clear he isn't the only)

I don't see how the existence of many antichrist implicates him as one of them.
