Well just to leave a comment: Yeah I think it's best. We expect of users to be pyramid shaped, so are the mods beholding to the pyramid.

Off topic replies can go, Ad hominem replies can go etc. (please do as mod give a PM shout out to how/why)

Where to draw the line between a sarcastic ad hominem remark wrapped into a 'on point' remark stays a bit for the mod to decide, I would handle it:

Like a post not belonging into a sub: PM the commenters say what's what and all. if they don't edit within a (normal) amount of time (12-24 hours) okay delete.

Then there is the "I'm going to reply' side, well stay strong within yourself, calling someone stupid (mild example) doesn't change anything and stupid people are going to believe that they are more right just because you call them stupid.

okay, and that's from a drunk Dutch person, you can shape up to be like me... NO! BETTER than ME! It's easy, very easy, and if it's so easy, you'ld be STUPID not to.

Also: This is what Wikipedia gives on ad Hominem: https://en.wikipedia.org/wiki/Ad_hominem (THAT'S RIGHT, THE PYRAMID!)!
