Criticizing people for all sorts of valid reasons and treating them decently are not mutually exclusive. You don't have to know someone personally in order to give a fair critique of their published ideas, or to know that the reason they sued you was stupid. Not everything is a personal attack (and you seem to take criticism of Wolfram more personally than he does. Note that this is an observation, and not intended as a personal attack on you!).

Again, I'm only defending the criticisms that I've read, which do not include Hecker's. They seem fair to me.
