I was going to make a similar post but you beat me to it.
Many Troons definitely have demons controlling them to some degree. Just look at Jeffrey Marsh - he is very clearly possessed by something extremely evil (as well as him being a wicked individual by choice).
There's no such thing as "summoning a demon", though. They are ever present and will appear to you if they so choose i.e. if it suits them to do so. All the ritual of summoning is just a sham, giving the foolish the idea that they might have power over such creatures, when the reality is the exact opposite. Everyone who wilfully consorts with demons is being manipulated by them. - YOU are THEIR plaything.
Oh yes they are. I've seen them in people. Had them speak to me.
Ask anyone who has worked in a maximum security prison or a forensic hospital if they believe in demons.
