I don’t think setting new rules without consulting other members fits into “Respect” principle …
Also,“Respect” isn’t something you can expect or demand. It’s rather something you feel without any intention toward others upon recognition of certain quality, to me.
You can certainly craft forum rules to motivate “respectful” people to post, and push away people without much potential for respecting.
But I think trying to force people to “respect” is a disguised form, a soft form of promoting and casting “blind obedience”.
With the kind of rules you set, I think the forum can become pretty superficial positivist hangout.
It that what you want/intended ?
Also, many religions (like monotheism) are highly condescending.
Will you ban any promotion of these fanatic religions?
Then, there is the offending the feeling of someone.
I mean, Atheist can be offended by the posting of theist and so on.
Anyone can be offended by anything.
I understand that you want to have “a good time”, but there is mundane bubble for that.
And do we come here to have “good time”?
Isn’t for thinking/discussing, even it means sometime we can feel being offended and we can make someone feel being offended (intentionally or not).
Personally, I don’t think “feeling” based rules are good choice, since it’s highly subjective.
It can also promote “victim consciousness/attitude”, too.
So, I’d suggest you to think over, discuss with other members, and revise the rules.
