That’s what I would expect from a generic (as opposed to clearly biased in the title, like “Christian view on creation of man” or something) encyclopaedic article on a topic, yes.

So the Earth article should give equal time to flat-Earthers, the Apollo moon landings should devote 50% to the "it was faked" idea, and Queen Elizabeth II's page should talk about her being a lizard person?

I think I'd prefer a useful encyclopedia.

No, but the “Moon landing controversy” article should.

The "Moon landing conspiracy theories" page on Wikipedia appears to consist of a thorough debunking. The only 50/50 it does is presenting the claims before knocking them down at length.

(As, I suggest, is appropriate.)
