Wikipedia articles are supposed to summarize “reliable sources” and be neutral among them, but not give equal weight to “unreliable sources”.
Here’s the thing: people have by now figured out that if you first define sources that say things you like as “reliable” and sources that say things you don’t like as “unreliable”, then you can turn Wikipedia into a propaganda organ for whatever you want.
Wikipedia is neither an especially good source nor an especially bad one.
