Unfortunately for those people it may be just best to ignore them and simply wait for them to disappear. They aren’t entertaining and it requires no intelligence to come up with a bunch of outlandish and ridiculous nonsense. They thrive off of getting a reaction from people and desperately want attention. It is no surprise that any acknowledgement of their existence throws them in to fits, they hope that their tantrums and ridiculous statements will cause others to get upset and perhaps say something ridiculous things as well.
It isn’t good to let people get away with genuine bullshit that they believe but a glance at those pages tells me those people really don’t even believe what they are saying, it is pure shock value. They likely are very anti-Atheist bigots but they are in no mind state to be talked rationally out of that, instead they hope that their yelling will just drown it out. There really is no helping those that don’t want to be helped and there is really no reasoning with a very fake Christian troll. Thankfully anyone with a little bit of eduction should be able to fairly clearly see through their propaganda and agenda.
