Gatekeeping a Progressive Movement by denying entry to those who do not meet your ideological standards, even though those people share similar frustrations, is pretty devisive.
Abdul El-Sayed is a great example. He bills himself as a Capitalist, but is pushing for socialist policies (socialized medicine, taxing the rich to support social initiatives, banning corporate home ownership):
When asked point-blank if he considers himself a socialist, El-Sayed didn’t flinch.
"I'm not. I'm a capitalist who just understands capitalism," he said.
He is a Democrat and refusing to support him because he doesn't fully align with what YOU think is the absolute moral position is very short-sighted.
Whether or not he follows through with his promises remains to be seen, but for now he is representing Leftist policies that I certainly want to see implemented.
