Back in the day, very sensitive people were run off non-sensitive places or made their own places to be sensitive in, to success or failure depending on what kind of sensitive they were and what kind of space they ran.
Now, the culture of the internet is so easy to access that it's an exaggerated version of IRL. Crazies of all colors spend excessive time on the internet, including a lot of sensitive people who now can ask mods to ban people for being insensitive to them. Mods ban it because they work for companies that show ads on your social media sites and don't want people to be hurt or the advertisers dropping them. Now insensitive people have to figure out communities of their own away from massive social networking sites that are easy enough for your old easily offended aunt or your young adult cousin who can't accept criticism in any way to use. These people also scare off normies, because you can ask people what social media they use and it's usually watching or looking at pictures for less than an hour a day thanks to the raving loons who screeched the rest out.
TL;DR: Sensitive people have more power and are more obnoxious than ever, kicking everyone who can't use or tolerate the system out.
