I know many times we like to post just to post, so I will say I am not assuming anything about the mods, as you creatively suggest.
Also, I am not an expert on loshon hora, but if you poskin it’s okay for you to engage in lowly, petty, disparaging talk only because you don’t know the real identity of “Joseph”, I would still say the yetzer hora has a bigger grip on you than if you did not give into the temptation to chime in on this ridiculous endeavor.
Finally, we are not expected to affirm every view in the opinion spectrum. If someone thinks differently, debate it or avoid that thread or person. To bash and bully someone for the reason they are
“extreme right wing”, is wrong.
It is said, “Scoffers have no place in the World to Come”. Are you sure Joseph bashing, even though you dont know his true identity, keeps your neshama as clean as if you avoided the situation?
