Thanks for writing.
I totally agree that misuses of reasoning, data, and clinical material can all be extremely damaging. However, when they appear in comments, they are teaching opportunities that I want to use.
As for the methods you recommend for dealing with hate speech, I know nothing about their use for that purpose and thus cannot comment on them at all. My part is to keep hate speech off my blog.
What _I_ wish would be taught as part of the basic educational curriculum are the documentable consequences of hate speech, such as impairing learning and performance, eroding self-confidence, etc.
