You're welcome here, and we don't need you to change your views, but we do need you to stick to the rules.
Being right and being able to bring it across in a non-offensive way are two different shoes.
Cheaper healthcare and worker's rights are universal left wing qualities.
The isolation he is pointing out is that instead of these principles, most discussion has been captured by fringe issues which alienate more people than they attract.
There are more strikes happening in the USA now than ever before in my lifetime. Most Americans want free, or at least cheaper healthcare. These are not isolated beliefs. The fact that this jerk wants to label a few things 'The American Left' and then decry them as isolating just means he either isn't paying attention to what Americans actually want, or intentionally ignoring obvious trends.
Frankly he's isolated and out of touch.
