I would agree with statement #2 and add my suspicion that some who seek religious divisions are agents of the left.
I agree, we have more than a few trolls on the “christian” postings.
generally it goes
“how can you be so absolutist!”
or
“god loves everyone, there fore he loves [insert behavior here}”
or
“the bible never said that”
or
“my church is more christian than your church”
or
some other troll phrase.
