Don't forget: There's nothing bad about no-response - People are much more likely to respond on the web and email when you're wrong. ;)

There certainly could be something bad about no-response. As someone in academia who gets uninformed musings or crackpot theories from laypeople in his mailbox from time to time, no-response basically means “I know you are wrong, seriously wrong (and, in many crackpot cases, probably mentally ill), but I am not going to just waste my time trying to tell you that.”
(I'm particularly horrid at email.). So I wouldn't take it personally.
Maybe the majority of recipients won't act, or they'll even take offense, but if somebody in there chose to contact you because they look up to your position, you could easily find in a few years that you challenged somebody to get on the right track with one of those responses. Some people are on the fence and looking for a push.
Obviously it's up to you, but I think it's worth a shot.
