Is it? This keeps being repeated, but I'm not seeing it in the general population. Sure, there are some loud people here and there, but overall it seems exaggerated to me. Of course, that's anecdotal, but still, I'm not buying it just yet.
I am aligned with the positions explored for the most part, but it seems like self-righteous offense inevitably emerges as a defense mechanism for these types of views.
Some people value being 'right' more than they value being happy. Some have an agenda or hidden motivation to talk down to others.
As long as there's an advantage to be gained from it there will always be individuals who bully others. Old school bullying has been replaced with 'moral' grandstanding and public shaming.
We used to teach kids, "sticks and stones will break my bones but words can never hurt me." At some point, that tradition was abandoned and some individuals shifted to assume the stance of 'perpetually offended' so they have a justifiable platform to attack others.
