Abortion, trans people, gay people....there are certainly MAGA issues that have even lead to shootings.
If I change my example to trans people...someone writes"down with trans" on bullets, same point stands.
But yes, if said person is in MAGA chat rooms, MAGA rallies, photo with hats on...then yeah can label. Same here - if this kid is in Antifa chat rooms, at meetups, has branding..then yes, label it. I'm not lumping them into a basket yet - just calling them a deranged mentally ill person for now.
