Much of the self evident and obvious "analysis" maybe. I am sure there is a lot of basic true statements in Mein Kampf. It's the rest that's the problem.

The person is quoting Marx to argue that we shouldn't have democracy. That isnt the "analysis" non-marxists will agree with. Well, neo-nazis might, but I doubt that's who you meant.

The quote itself makes little sense and doesn't provide any insight. It's just a statement without any reasoning behind it. It only provides "value" to those who see Marx as an authoritative philosophical figure, which is pretty much just commies.
