You do understand that I recently made this point in this very thread, right? I was specific in my comparison and its significance, and I have said that we should be vigilant.You do understand that Hitler didn't start by invading other countries and murdering millions of people. If you wait until something is at the scale of the holocaust to call out the danger means you will always be too late.
But, calling something a Nazi salute when it isn't is not the same thing, which is how this current discussion started. IMO, if people are going to compare two things, then they should be accurate and they should explain the significance of the comparison. There may be some similarities, but if we are going to make comparisons, then be accurate and engage in critical thinking. So many people call things or people Nazi or Hitler with little or no analysis that it can sometimes trivialize Nazis and Hitler and also just makes others ignore what they are saying. Plus, unless we understand the complexities and nuances of a particular group, we cannot counter them and prevent their dangerous beliefs and actions from spreading. QAnon believers and their conspiracy theories are different in many ways from Nazis and from other right wing extremist groups. QAnon is based on a whacko theory that there are elite Satan-worshipping pedophiles in government, business and the media. Their catchphrase and the associated music and arm gesture may be evocative of the "Heil Hitler" phrase and gesture, but it is not the same.
