If everyone was happy and insular, sure. Plenty of space for people who enjoy the hobby differently.Isn't this a live and let live thing? If you are not into Jesus-D&D, or Old School-D&D, or LGBT-D&D, or whatever type of D&D, that is fine. One can stay away and let those that like that style play their way.
It is nice that the OP let everyone know what is going on, but the way it was put out certainly tries to portray it as badwrongfun and not informational.
I like Desmond Tutu’s quote:If everyone was happy and insular, sure. Plenty of space for people who enjoy the hobby differently.
However, once a group starts attacking others, then silence/live-and-let-live favors the aggressor.
MLK Jr. said "There comes a time when silence is betrayal", and it might be more explained by anti-Nazi German dissident Dietrich Bonhoeffer who said "Silence in the face of evil is itself evil: God will not hold us guiltless. Not to speak is to speak. Not to act is to act."
Basically, once it crosses the line from "we have our fun different" to attacking others because they don't do things the same way as you, live-and-let-live is no longer an acceptable action unless you endorse their attacks.
