The group that Alex belongs to also thinks that the “rapture” is a joke and that Pentecostals, Methodists, Baptists, Lutherans etc. are heretics and/or follow a “satanic gospel”. This group’s doctrine preaches hatred of all us Christians.
There's a lot of that going around on FR and they're all so obvious that they're funny. Of course they prefer Satan, he self-elected the same way they self-elect. So for them, what's not to like about Satan?
