Generation Z was witness to “Gamergate”, is aware of MGTOW and “The Red Pill” theory. Watches alternative news and discussion sources like Stephen Crowder and Stefan Molyneaux. They also grew up on the internet and aren’t fooled by Share Blue troll types.
Al Gore is going to rue the day he invented the internet.
Gamergate is huge. Anyone who does not recognize the term has NO IDEA what a culture war landmark it is for young people.

The rash of Sanders inspired Socialist memes aren’t going to change that, kek.
