I agree that the number of proponents of something like "LatinX", or "biological males playing women's sports" are far, far outnumbered by the people who aren't supporters of those things. But the issue is that the people who are supporters tend to be extremely vocal and generally in positions of power or better able to influence those who are, whether thats in corporate or academic administration settings. As such the small number of "woke" individuals are having outsized effects on society and culture, and the backlash is in response to the magnitude of that influence, rather than the number of people pushing for it.
Or are you referring to 1990s definition of mainstream media that isn't mainstream and is irrelevant?
