The real issue here being missed by most is the self righteous attitude of the left. The belief seems to be that disagreement with progressives is immoral.
In the OP's link someone asks the question on twitter - would Norris oppose those parkland survvors who are pushing for gun control?
Norris probably would oppose them as do many others.
Being a young survivor of a mass shooting does NOT give you moral authority to push a political belief onto others. Opposing the parkland kids and their views is not callous or immoral or wrong. They have no superior claim or experience than anyone else allowing them to dictate politics and policies unopposed. When they are wrong they are wrong regardless of their traumatic experience.
And they are stupidly wrong about gun control
