Regarding the shooting incident today by a Bernie Sanders supporter attempting to murder Republican Congressmen: this is what can happen when someone allows politics to define their life: extremism. This is why I urge people not to let politics distort how they view people. Those with whom you disagree are usually people like you. When we dehumanize our political opponents, this type of behavior can occur. This guy was clearly an extremist on the left, and it can happen on the right, as well.
Also, the Capitol Police who responded are real heroes! They prevented a massacre from happening.
