You will never be sure. Nothing can make you sure. If he were to the right of Barry Goldwater you wouldn't like him.
SANE people realize what he was saying was "when someone is reported to the police to be acting crazy,you take his or her weapons away from them until such time as they have been given a clean bill of health. You do NOT wait until they carry out the mass murders they have been saying they want to commit,and THEN take their weapons away from them.
And it should NOT need to be said that when the cops pick someone up and take them to a mental ward for evaluation,they do not have access to their weapons.
WHY is common sense so uncommon these days?
So you have a Mr Social Justice Warrior, let's call him David. Well David really hates gun owners. He sees many comments on local news articles by a man named Pete defending the NRA and gun ownership. So David decides to take action. He and his friends call their local police chief (good old progressive guy too) over and over making accusations that Pete is mentally unstable. They don't really know Pete or if be really is, but in their mind, anyone who thinks like Pete is a danger to society.
So Mr police Chief, listening to David and his friends, confiscate all of Pete's guns with zero due process and very little recourse.
This isn't crazy, it already happens with parents having children removed by CPS for the parents beliefs. It ilso is how SJWs stifle speech on social media.
