I think this is covered by rule 1.2; everybody is entitled to have their own opinions, but should express them in a respectful way.
In no case should your opinions posted in this forum make people feel uncomfortable (that's what we mean with "bashing people"); more so, if they explicitly state it's happening and other members of the community express this concern.
There are no "right" opinions, but this is not a place to discuss that; all the Codex seeks is to maintain the harmony of this place and prevent discussion from being ruined with inappropriate participation. That should not be tolerated.
