That is a person who is suffering from a true psychological issue. There is nothing else that would cause someone to spitefully treat a dead parent poorly and then brag about it to people. Certainly not political ideology. I hardly think that would cause a mentally stable person to abandon all love and caring for a parent to the extent that it would carry on past their death.

At the same time, this is unfortunately who you have to assume you are dealing with if confronted by a wild eyed member of these groups that have been rioting for the pat year. They will not allow you to walk away peacefully, they will use deadly force against you without remorse. Be prepared, be vigilant and let your aim be true because it will quite literally come down to you or them and you want it to be YOU going home to your family.
