Just a suggestion..
If you want to start a topic, for which you feel some responsibility to ensure the discussion does not become undignified, by those neglecting the path of appropriate speech; if you will, please post a link in THIS thread, to say that there is a topic in your PPD for a dignified discussion.
It doesn't necessarily need to be about your own practice, but you will be the host/mod for that discussion and delete abusive or trolling, unnecessary posts as you see fit.
As some old Daoists have said, "when justice is not regulated, people are less likely to commit crimes than when the punishments are arbitrated by judicial systems and not the common people," so don't be too surprised to hear this from a Chuang-Laoist .
This is not to say that no-holds barred conversations are not also necessary, but I think this provides a useful option to mod as you see fit.
Of course over-governing will just end up in trees fallin' with nobody to hear 'em.
[edit: and hating on someone while deleting their responses would just be abusive and against TTB regulations on haterade.]
