The first part seems rather applause lighty; I think almost everyone agrees that we need to distinguish between ideology and fact; actually doing so is the hard part, and the quote doesn't provide any interesting insights in how best to go about doing that.
This is probably me projecting, but I took it to be about distinguishing between those which make claims about reality and those which don't.
For example: If somebody says "You should be democratic, because the people have the right to rule themselves" - that's not even claiming to be a fact, just an ethical position. If they say "You should be democratic, because democratic countries do better economically," then that's a about the real world, which I could even test if I wanted to.
In my admittedly limited experience, it seems that a lot of confusion in the greatest mind-killing subjects (politics and spirituality) come from people not properly distinguishing between those two kinds of statements.
