Wikipedia is not a dictionary. It mentions that homeopathy is a pseudoscience because it would be a glaring omission for an encyclopedia if it didn’t. Homeopathy is a medical system that works as I described above, and it just so happens that it’s totally junk as well. Its usage in the context of those that practice homeopathy is not the definition that describes it as being bunk.

Similarly, “based” is used to mean the opposite of “cringe”. It just so happens that most “based” content is what others might call cringe; the video I posted above is satire of exactly this. However, it doesn’t change the meaning of the word, and in fact the joke falls apart if you redefine it this way.
