If you're worried about empowering the far right, the worst thing you could do is refuse to look at reality because occasionally some far right nutter talks about it

Indeed, because once we start doing that then we allow the right to monopolize anti-establishment and anti-imperialist rhetoric. You don't diminish the right by doing that, you diminish the left and drive people toward the right. People, by and large, realize that something is not right and they look to whoever will validate that feeling and give them an explanation. If the left fails to do that then the right will. The surest way to alienate people who are just beginning to have some nascent class consciousness is to give in to the liberal moralizing impulse (of which the ultra-left purity fetish is a manifestation).

If a right wing source presents a correct geopolitical analysis then we need to acknowledge that, otherwise we just discredit ourselves. And then, if and when they go on to state nonsense about other topics we will have the credibility to say "no, actually on this topic they are wrong" and explain why and convince people that we communists have the more correct analysis on the greatest number of issues, because we do not make the idealist errors that the right does.
