Certain ideas on the left are intensively conservative. For example, "We can't solve any problems unless we get rid of the billionaires and replace capitalism as a system." is effectively the same as "We can't solve any problems unless we pull this sword from the stone, so status quo for the next 100 years I guess."
I'm blanking on the other examples. The gist is preconditions to solving a problem is intensely conservative (in practice), even if those preconditions are left wing flavored.
