Of course you have the right to vote against your own best interests and elect someone who will harm you. Why force that on your kids?
What right do parents have to subject their children to an evil doer? Parents are supposed to protect their kids and look out for them. If they can't even do that what is their purpose? They are useless, toothless and shameless.
Well, yes, of course you are right.. but... but.. I am afraid that the people you are talking about, the plebs, the stooopid who voted for Trump - are probably bad parents too, so they aren't going to care.
