Yes it's a muddled mix but two things jump out quickly. One you're not going to get attention marching with notepads and whispering. And two they don't need to cater their message to anyone's ideas but their own you are asking a totally different generation to appeal to another. Yes it might be a better political idea, but this is a young emotional movement. I don't know how people can expect a sophisticated perfect message and a completely unified front... It's just not realistic
I'm not saying you have to go to demonstrations if you dont want to, but if you want to find out the truth though you probably should it is worlds away from what you are describing you just said your only experience is through news and online forums. Yes there will be some messaging like that. Obviously I don't agree with that, or lots of other ideas and sentiments, but I still listen to everything they have to say. There will be a few extremes and colorful language but do all those folks really want to kill marshalls? Highly doubt it. Again it's getting attention and people are pissed off... These are young activists not campaign managers
