Exactly. No need to be rude - people just need to remind them that they live in a country where anyone can buy an automatic weapon and their President is acting as the perfect recruiting tool for lone wolves.
Then ask them if they think anyone should be able to buy weapons?
Then ask them how Trump is keeping Americans safe if he allows anyone to buy weapons even if they are now starting to hate and they live legally in America?
It might make just do something to their brains..
Or just tell them they're going to need weapons when the next lone wolf attack happens in the USA from one of their own.....an American.
