This is just an observation from those who tend to subscribe to leftist philosophy on this site. Take it for what it's worth, and discard the rest.
I personally believe that many of the articles on JoeUser that have been put forth by centrist writers or others who see "both sides", but have veered right have been for one simple reason: Because the nature of most who would describe themselves as "left" is to act on "feeling" and emotion, and because it is far easier to "get your goat" by using certain keywords to elicit a response. Many on the right have become aware of this, and also have become aware that the best way to get noticed is to create controversy.
You have compelling and interesting points on many of the issues, and although there are many on the right who would agree about the solutions that you propose, there are a fair number who could be convinced, at least, that there IS a problem and work towards solutions of their own. Which is more important: that racial injustice, poverty, and inequality be solved YOUR way, or that they be solved by individuals from all sides of the political spectrum using solutions that are amenable to all? I guarantee that, no matter how you personally answer that question, there are 1.1 billion poor in the world who would prefer to HAVE food than to question the manner in which it was obtained.
There are times to divide, and there are times to unite. When we divide on EVERYTHING, we only succeed in lessening ourselves. Right now, in the context of the popular media, you "have the floor" in America. You can use that platform any way you choose; my personal suggestion is that you use it to discuss strategies to build a better future for us ALL, but that you give equal time to opposing views to present alternative solutions.
