As a Gen. Z-er, I can confirm that it will be horrifying.
Could you elaborate? I have this nagging fear that the politics of Generation Z will be defined by Tumblr-type SJWs vs increasingly openly racist Alt Right types, though the meteoric rise and popularity of Bernie Sanders with our nation's youth gives me hope that an actual Left-Wing Movement that prioritizes building a social safety net and reducing the inequality brought on by globalization may yet emerge.
More than half of my age group has already decided that it's funny to support Deez Nuts in 2016 and Kanye West in 2020. There are some moderates, but the moderate ones tend to be less politically involved. As for your fear, don't worry about it. I've never met any SJWs, and although there are a few alt-right people who probably spend a bit too much time on r/theredpill, I seriously doubt they'll continue to hold said views.
