Eric, not all Calvs decry Kaths as being Satanic; Jaxxen doesn’t, including in that quote you provided. Some Calvs are willing to allow that Kaths can be in the process of regeneration and so desire the truth and living God. Calvs generally believe errors about God will be corrected for the elect eventually.
Also, false teaching isn’t necessarily morally malicious in intention: teaching falsehood isn’t necessarily lying, it could just be teaching mistakes. On the other hand, someone could be teaching the purest orthodoxy and still be a false teacher in malicious intentions. (St. Paul has some things to say against teachers abusing his audience even though he’s glad that even by them the gospel is being spread, for example.)
We try to be lenient to newcomers who don’t understand this forum isn’t a place to accuse other people of serving false gods; TD was only here a couple of days before leaving for a while, so he wasn’t here long enough for the ad/mods to start serving him formal warnings. We have been extremely lenient about universalist members accusing other people of serving false gods, too, and non-universalist members have a right to complain about that, since it smacks of favoritism.
That being said, it remains a fact that we’ve chosen to eventually ban more universalists than non-universalists from the site over the years (probably due to the relative population numbers involved). I don’t know any universalists who are currently being considered for banning, but it might be of some reassurance to non-uni visitors.
