What is QAnon

Hello, I hope I’m not offending anyone but this subreddit seemed like a good place for answers. Also, I’m sorry if this is the wrong subreddit to be posting this to. I read an article by the BBC, but what do QAnon people typically believe in. What is QAnon? I think I was left with more questions than answers by reading the article I mentioned. From what I’ve seen, I summarily took away the idea that Trump is fighting against the elite Satan-worshippers in government, media, and business. Is this correct? That’s what most of these QAnon people think? Thanks for any replies and clarifying my confusion.

Edit: I seemingly upended one freaky iceberg. Thank you for all your help and comments!
