There is only one principle that is truly important when it comes to this so-called "Sensitivity". It's about control. Be it feminism, men's rights, environmentalism, veganism, LGBT rights or whatever the social policy is, the loud minority who makes it worse for everyone else are all about getting control.
The word cry bully rings true because that's what they are, bullies. The so-called SJWs harass people, DOX those who disagree, insult anyone, physically threaten etc because that control makes them feel important and powerful. If you watch a video of some of those campus trolls who scream at people for microaggressions or loveism, they're always enjoying it. They're roostery, smiling, reveling in the power to inconvenience or attack somebody and still be righteous in their mind. They go out of their way to do this because they find it validating.
It certainly may seem like the norm because of the oversaturation of media. It's a really easy spin, "Liberal Hell". The majority of people aren't like this, the majority don't even give a flying forget.
