I'm not going to tolerate that kind of negative stimulus being applied to community organizers.

Yes.

I think it might actually be a good idea to give any poster the power to delete replies in their post's comments thread - Facebook does this automatically

No.

A Facebook page is a personal fiefdom within which one has absolute power (within the limits of what one's feudal superiors, i.e. the owners of Facebook, and beyond them the state, allow). The same applies to personal blogs. Making a post or a comment here puts it up for grabs by anyone. That is what a discussion forum (which this is) is for. I specifically do not want that power over replies to my posts here.
