The 'social media'/internet presumes a certain 'accepting', inherently socially liberal order amongst its users. As more and more people who don't fit that use the internet, there will be greater hate and rudeness and intimidation in the internet, and the happy-go-lucky we-are-all-one destroy-the-borders liberal dream will end. The internet will start reflecting the extremes of our behavior, and it will be ever the scarier for women and minorities.
It'll be interesting to see the evolution, and how it's handled.
