Mashiach Agent, you wrote that it is upsetting when the mods don’t let posts go through. That is what Coffee was referring to, I believe.
In any case, bottom line is that there are people who get insulted, and there is no toeles to posting other people’s insults. I am talking about things like Reuven criticizing Shimon’s grammar. If Shimon finds it offensive, it should not be posted. If Reuven is upset that his post criticizing Shimon’s grammar was not posed, then Shimon is the one who has issues.
