As much as I agree with the author, you cannot have a logical argument with illogical people. We are dealing with illogical people. They do not want a discussion. They don't want an argument. They want their way at any cost to the rest of society. This letter will resonate with those who feel the same. It may cause a few others to wake up as well and that would be a good thing. But the author will not sway the minds of their colleagues.
People don't change because they see the light. They change because they feel the heat. Those that don't change even then, get burned. Those that still refuse to change get burned up.
