Unwanted Advice,( Rant)

I've noticed for a long time, that there are certain members, (you know who you are)that consistently post negative opinions about subjects that they admit to having no experience with. Especially on the Camp Cooks category, people will post/ask very specific information for those that are interested. If someone posts about, 'Sous Vide', for example, if I'm not interested in that, I skip it. I really don't appreciate certain members posting their very negative 2 cents. These same members never say, 'That sounds interesting.'. but always something insulting and degrading.
These negative comments are not welcome. They don't add to the discussion. In fact, when I see that a certain member has posted, I know pretty much the content of his/her post. Let's remember that if you don't know what your talking about, keep your mouth shut! Rant over!
