This kind of vile malicious partisan bull crap makes the folks who spread this crap part of the problem (where folks seem intent on sowing discord rather than working together) not of the solution. The idea that because folks in a different party want to take different actions to make kids safe than the folks in the other party it means they "do not care about < in this case they add this: insert race> children".
This is nonsense. Parents that lost children in Parkland disagree with other parents that lost children in Parkland and these folks would say that they literally didn't care about their children because they disagree on what policy would help protect their children. It's vile, beyond disgusting, and definitively is the cause of why folks will not cross the aisle to ever pretend to aid someone that believes this about them. Those that do this are political filth.
