If you publish anything on a public forum you invite criticism in so doing!
You do not criticise those who write supporting your views albeit that is as much a comment on your posts as the critical remarks of others.
All contributions have their own validity, whether you or I like them or not is not really germane in this context.
Finally if responding to anothers posts in a totally non critical way either for or against was a rule on this site, there would be a lot less posts, and a lot less of interest to those who frequent this site.
