Why is this attitude so prevalent? You make an extreme and unsubstantiated statement denying any merit to one side of a contentious issue. Somebody predictable comes along and argues that there is demonstrated merit on that side and it must be acknowledged if we want to improve upon it. And you respond with disdain, so sure that anybody who dared question your radical position must be totally blindly loyal to the other side to the same extent that you are to yours. What do you or anybody else gain from that? If I'm just responding to a troll account then I guess that's on me. But if not, please explain your motivations. Why are you publishing far-out opinions and then lashing out when disagreed with? It's exactly how anti-vax advocates and flat-earthers behave.
