Well I have no idea what you mean by public activities. I can only guess at the intended scope. Perhaps, instead of calling people with carefully measured and carefully considered opinions, right or wrong, you could stop the kind of misinformation which is constantly peddled here. There is a large error in the post of 04.25pm for example, that can be checked in ten seconds, from a person I never see you criticising. I submit to you that a closely-argued opinion, capable of being civilly disagreed with, is far less damaging than blatant misinformation.
