People's minds have become jelly, and with the slightest challenge in life, such as a tough relationship, they are more and more willing to go into public places, take out that person, and anyone else who just innocently happens to be in the place at the time, and then (usually as is the pattern) just "off" themselves.
A sign of the times.
This statement is neither pro nor anti gun, just a reflection of what America is often becoming IMHO. People cannot handle adversity (layoffs, personal challenges, arguments/strife) i.e. that which they once were able to do by "manning up" and could do relatively easily. Weaklings. Moral cowards. Human rubbish, actually. Worthless. And now wards of the state for the rest of their life, on the dole, out of our pockets.
What you said. The intense Self Esteem training that seems to be the primary raison d’être in public education would seem lead to just this outcome.
I agree.
