Hi far east.
The way I see it, it is not the topic. It is the poster.
There are relatively harmless topics in here and machlokes and all types of loshon problems come up.
We all have to work on those. But if someone is not willing to do that, then write them up as another internet bully, Jewish, informed, or not.
It may not be deliberate though. We all have our issues to work on. For some, they can not resist “going there” because communication is with a screen and not face to face.
