No, it has to do with the hypocrisy of leftists thinking it's OK for them to exercise their second amendment rights, because they have a "just cause", meanwhile they'll still try to take away other peoples gun rights.
And school shootings are a product of something other than the 2nd amendment, back in the stone age when I went to school we brought our guns with us to keep in the locker until after school to go shooting.
I remember a day me and my friends were walking down the street all carrying rifles and a cop driving by us not thinking a thing about it, something has changed causing the mass shootings, it's not the guns, my guess it's all the ADHD meds every hyperactive kid seems to be on.
Because whereas we used to go out and play and burn our energy off kids today dont do that, they all have an XBOX controller in thier hands plopped in front of the TV taking meds because mom would rather have a zombified kid than have to deal with all the excess energy that was done in my day by telling the kids to get out of the house and go do something.
