Until now no one cared what PM said or thought about anything. Not too many people actually watch his show. He is probably elated at the attention he is receiving. He will be treated as a hero in his home country for standing up to the gun culture and gun nuts in the US.
The PM mania displays the mindless paranoia of gun freaks. They get up in arms in knee-jerk fashion over any statement about guns that doesn't agree with NRA policy.
Even in the lawless old west, cowboys had to sometimes check their guns before they came to town. No one considered that unconstitutional. It just made good sense. Nowadays commonsense is considered stupid thinking and we want to deport those who are using it.
