I think we were in the same zero waste group! I left because a post I had made about ecologically responsible farming being possible was refuted by someone just giving sound bites without knowing anything about regenerative agriculture. The problem is that people refuse to look past what someone else tells them and realize that there are other ways of doing things and the problem isn't as black and white as they are being lead to believe. It is easier to believe that something is one way or it isn't than realize what you believe is wrong. Then these people get defensive and those that actually researched something get frustrated that someone could be so close minded. And usually those that are so close minded are the ones saying we need to respect people who are different. (at least until your different doesn't match up with their different)
