Nan,
Would like to say that I'm surprised by your OP but I'm not, considering the tenor of this board most days and how truly exhausting moderating can be.
I've been a part of various incarnations of this board since the 1990's, primarily lurking. We have a truly EXCEPTIONAL group of moderators here and it infuriates me that any one of them has been so emotionally drained by their moderating here that they have reached the quitting point. I've moderated a baseball board for 15 years or so know the feeling, unfortunately.
Here's my input to posters, FWIW -
1. This is a privately run message board. You, as the poster, aren't DUE anything. Owners' rules, period. You aren't even due an explanation. If you GET an explanation from a mod, consider that a gift - NOT the opening salvo in a debate. If that seems arbitrary, you don't set the rules.
2. Exercising tact and diplomacy in your posts really is beneficial for you, personally. There's an old saying, "You get more flies with honey than vinegar." Since both your off-line personal and professional life will benefit, consider it good practice to do it here.
3. Participate as if you are having an in-person discussion with your dearest loved ones. If you wouldn't say it to them, don't say it here. If you WOULD be nasty, snarky and confrontational with your dearest loved ones, I'll point out that, contrary to the Hallmark cards, love is neither eternal nor infinite. Nasty, snarky, confrontational (and abusive, dare I say) can eventually wear out the deepest devotion.
4. For those posters liking to 'mix it up' on any particular thread, try to keep in mind there are those posters that simply enjoy the team and root for them. They aren't interested in having to validate their fandom by engaging in a debate with you. There are many shades of fandom and they are all fine.
5. If you truly feel too constrained by how things operate here, there are other more...free form, shall we say...boards that might be a better fit. Or if you can't find a true fit elsewhere, start your own board.
Stepping down from my soapbox.
