Ever heard " you don't really understand something until you can explain it to a small child?". E.g Germany for the Germans. It's so simple a child can understand it.

Leftiest don't understand their ideas well enough to explain them simply.

That's because their ideas need a bunch of theoretical beliefs that need a vacuum to exist. It's basically words salad that makes no real sense and people only accept it because they don't want to seem dumb or cruel
