Jimmy Fallon has a funny way of approaching his late night gig.

The former “Saturday Night Live” star thinks it’s all about making people laugh at the end of the day. It’s not divisive, or corrosive. The “Fallon” method treats guests like … guests. Politics are fair game, but it’s not what matters most.

Think lip sync contests and skits bound for viral glory. And that was fine before presidential candidate Donald Trump sat on Fallon’s “Tonight Show” couch last September.

Everything changed at that point … for the media.

Fallon didn’t just treat Trump like any other presidential contender during that interview. He “normalized” Trump, using the modern Left’s parlance. No hardball questions. No outrage over Trump’s campaign antics. And he did the one thing that enraged liberals the most. Fallon playfully tousled Trump’s hair.

The horror, the horror.
