Is Lil Nas X a satanist ?

He made red shoes, so he's clearly a Satanist.

He might be.  But most people who identify as Satanists are really just atheists; they don't believe in Satan literally.  

No, hes just mocking people who told him hed go to hell for being gay, so he made a video about it. I cant attest to the accuracy of the video however....

No. He's a shock artist. He's exploiting shock value to increase his fame. Ozzy Osbourne did it way before Lil Nas X. So did Madonna, although instead of giving Satan a lap dance in a video, like Lil Nas X, she got down and dirty with a saint in a video and danced half-naked with nothing but a black slip and rosary beads on in front of burning crosses. Instead of selling sneakers with blood in them, she sold a pornographic book called Sex.

Yes or he's an agnostic pissing people off for attention
