If people from different demographics didn't interact on social media then nothing would ever go viral. The limitless exchange of information goes beyond geographic social circles and instead starts to impact all of society, that's what people mean when they say the internet has its own culture. Which is why the controversies surrounding Captain Marvel and Disney in general has taken on a life of its own. It's not a 'culture war' as some burnt-out postmodernist from the 60s would understand it, this is a war of technology between the legacy media and the user generated content of the internet. Attempting to define Captain Marvel's critics as one group or one ideology misses the point completely.
