Here's one possible way to implement this that wouldn't relate to the NPOV policy: don't remove links, simply deactivate them. The same information remains for anyone who wants to cut and paste the URL into a browser manually. The article content isn't affected. What does get affected is the outgoing traffic from Wikipedia to the site (since a lot of people are lazy), and Wikipedia is a very considerable source of link traffic. This doesn't need to be done on a permanent basis, just as long as...say...a certain editor got specifically targeted on the home page of Michael Moore's website.
I haven't pushed this idea particularly because another editor whose judgement and experience I very much respect asked me not to. I'm not necessarily advocating it now, rather presenting it as an alternative perspective at a polarized discussion.
