The notion that liberalism/progressivism is the one and only home of "special snowflakes" who flip out over others expressing their free speech and can't handle hearing other opinions doesn't hold up to the facts. It's not young progressives who are currently ranting and raving about the new Ghostbusters movie, it wasn't them who organized and took part in the mass complaints of Gamergate or Sad/Rabid Puppies, it's not them who frequently throw fits on the Internet about "Censorship!" or "Pandering!" if a video game dev chooses to remove something politically incorrect from a game or add something politically correct to it, respectively, and so on. Donald Trump himself, perhaps the patron saint of awesome manly men who are too badass to care about being politically correct, was triggered something terrible when Megyn Kelly asked him unflattering questions during a debate, so much so that he refused to take part in the next Fox News debate. What a crybaby/beta/cuck/pussy, amirite? Oh, no, those terms only apply to liberals or progressives when they complain. When conservatives do it, it's ethical and admirable.
Every demographic has its complaints and protests. Sometimes they're justified, sometimes they're not, but they're nothing new, and they're certainly not a product of this one specific coddled generation of liberal college students. To give a more positive example, I'm pretty sure that the people who give the Westboro Baptist Church grief (blocking them from view at the funerals they protests, drowning out what they have to say) skew both older and more conservative Of course, nobody bothers writing articles about this terrible suppression of the WBC's free speech, and what it says about the spineless generation that can't bear to hear differing opinions.
