A chat on 4chan

Yes, one of my friends became (what i'd consider to be) possessed after taking meth.
He came into a psychosis and had to be admitted to a psychiatric ward and when he came out he started a cult which was based on what two entities ('Gods') were telling him. It basically was made up of warped, incoherent Gnostic-ish ramblings and to be in the cult you have to identify as either being a witch or a werewolf.
He actually managed to lure a dozen people into said cult and they come together on full-moons + on pagan holidays, where they do his versions of different pagan rituals while drinking and taking drugs. 
I've never been to any of the gatherings but my friend B was once and he said it was just a bunch of addicts and teenagers who 'just seemed to want to belong to something and were desperate enough to come to him'.

Me and my friend B went to visit him last spring (we three used to be somewhat tight at one point) and it was incredibly awkward and sad to see him in the state he was in.

To say he was weird is the least I could describe him. Just to mention a bit of it all: 
He wanted to share his 'Gospel' which the God's Anu and The Lady had given him, insisted that my friend B would give him back the 'invisible book' which he had given B in a dream and then spent a good amount of the time meowing in a corner.
At one point it seemed that he became cognizant of his state of being, as if his real self - our old friend - resurfaced when he told us
'I... I am plagued by bad thoughts...' and then he went right back into the crazy abyss.
It was heartbreaking to say the least.

tl;dr don't do meth, kids

Recently, I've been hearing a lot of complaining about muh gnostics. Hmmm.

On brazilian image boards too, several are from Christian's discord channels that coordinate those posts, basically they found a new subject to attack based on what famous christian youtubers says, lol.

What is their problem with Gnostic ideas?

They don't believe their god can have an enemy as powerful as the demiurge and many are simply not ready to abandon the Old Testament and deny the pleasures of material world, not to mention that their view of the Gnostics is the one forced by the Catholics (the church that killed all Gnostic but left the Jews alive and hide ancient knowledge on their libraries, kek).
