By and large I agree with what Mr. Moreno says, but his statement that ". . .  he has shown once again how elitism has overtaken liberal thought.", is such a broad brush statement as to simply not be true. I could pick out any number of letters from the other side of the political spectrum and use them to bolster an argument that conservative thought has been taken over by defeatist and reactionaries, but that would not be true either.
It's easy to fall into the trap of labeling and pigeonholing a whole group of people based upon on what just some of the more extreme people of that group may say or do, but that just plays into hands of those politicians and power brokers who benefit from the "us against them" mentality in this country, and want to keep it going for their own personal reasons. 
There are a lot of people in this world (e.g. N. Korea, ISIS, Russia, etc.) who would like nothing better than to see this country collapse from within. Let's not let it happen.
