Not everyone that is on those Christian facebook sites is a Christian. There are many “fake plants” to get folks banned. Just like sodomites infiltrated the Catholic church to bring it down.
I heard about that a decade ago in Canada. That there fakes on Free Dominion trying to incite libellous words to start lawsuits. Yes I call out the trolls when I can. I ask them if they hate religion why are they on a Christian site.
