I wouldn't call it failure to understand or laughing at another's pain, but I see it more as being exasperated by the fact that you have pain in the first place.
The generations before you were in a tough mindset after the death of another person...or seeing their friends blown apart. To see the effects of death and destruction right in front of them.... To see people dying...
As opposed to this generation which it appears is in the same mental place, but instead of death and destruction, it is from them not getting their own way. The election didn't have the outcome you wanted. People are challenging your beliefs, and you lack the ability to stand up to those challenges. You're coming to the realization that you won't always get your way, and that is upsetting.
At least...that's what it appears to be from this angle.

It’s a slap in the face to those who legitimately suffer from PTSD due to the trauma they have suffered.
