See, you are learning to ignore the nuts.
If you don't learn to ignore the occasional nut and you toss out the whole movement, then you fall prey to agent provocateurs very quickly and complete government control. Same thing with Benjamin Dichter. Most of us knew he was bad news and a fraud from (near) the start (a spokesperson for the truckers who only ever drove a half ton and was associated with political parties.)
So a few people sent a MOU to the government demanding their freedom or that the ministers resign. Who cares?
Should I be willing to walk away from a protest because not everybody there represents what I do? I have heard everything from "hang the politicians for treason" to "pray for the politicians." I am there for my own reasons. Just because somebody sends a MOU or somebody demands that a politician hang does not mean that I agree- but it also does not mean I'm leaving. The idea to me of a freedom protest is that you are free to have whatever belief you want as long as your actions don't cross the line into being very wrong (note that I did not say illegal as the two are not always the same anymore.)
So yes- I can see a hundred thousand good, honest people who are just there peacefully protesting and ignore the one, single nut case who is screaming something racist or the single person writing a MOU. Are you able to look past the thousands of nut cases burning a city to the ground to focus on the other thousand people whose intentions are good and honest and decent? If so- why do you demand that I only focus on a half dozen people and ignore the good that came out of it?
