perpetual petty drama
Please note that passive or actively aggressive comments like these are the petty dramas.
Your attitude when things don't go the way you like seems to be the entire cause of these dramas. Nobody wants to constantly read seething posts or comments. The answer is not for the board to just give in under those kind of pressures but rather to resist toxicity. Nobody is ever going to miss not having to read an inflammatory post.
I hope over time you reflect on how you present yourself to others and have an epiphany of sorts and begin speaking non-violently.
