In the past at times i have been harsh about your pushiness on certain requests. But i have recently realized it was most likely you just being passionate about your view of a better world and perhaps getting frustrated about people not getting on board and working with you to bring it to fruition. That is an understandable reaction and in the end your goals are and were worthy of discussion and merit. So just wanted to say that.
That said I suspect if you took that passion and perhaps tweaked how you approach people a bit, you could get much better results. Some of it is just working with peoples short comings and not anything wrong you did yourself. For example long messages will automatically exclude 95% of your audience and cause most of your views, however valid, to go unread. Cant fault you for putting time into expressing yourself fully but regardless of how people **should** respond we live in a world where should isn't is. If you adjusted your message to be more easily digestible along with a few tweaks to how you otherwise interact with people I think it could go a long way at getting you a better response and backing to your goals.
