There are a lot of these stories about Trump out there. As much as people bash him, there’s some real character there as revealed in a number of actions like this.
My favorite story is Trump stopping a beating on the streets of NYC. In the 80s a low life mugged a guy and then proceeded to beat him with a basedball bat. Trump got out of his Limo and told the guy to stop. The mugger dropped the bat and ran. I can’t think of a single rich guy who would put himself in danger like that for someone he didn’t know.
As far as I know Trump’s never repeated the story during the campaign. Trump’s just one of those guys who doesn’t parade his good acts for professional gain.
People are so indoctrinated by PC that they no longer give credit to people who may be a bit abrasive sometimes, but still have heart and empathy. Trump is a good guy, tough and brash sometimes but a good patriot guy.
