Got it, you don't actually think bickering is useless, you just want the people who disagree with you, even partially, to shut up. Very cool.
You clearly know nothing of the social/working movements of the early 1900s.
Why would that be relevant? That was a century ago. The world is different, people are different, there's been a century of anti-left propaganda. It's a fundamentally different situation. You can't keep trying to use the 19th century playbook on the 21st. Update your models homie.
