Stop. You've lost the plot. This particular thread of discussion was not about Trump himself, but specifically about Trump University.
Again, this is about Trump University specifically, but... Yes. That was the point of questioning the claim that Trump University was a "failure". It's likely that it was actually fairly successful at achieving the goal it was intended to achieve: swindling people out of their money.
Did Trump just challenge Joe Biden to a bout of fisticuffs?
No, that's not a challenge for a schoolyard fight. It's just the usual taunting of our President, a statement that if they fought, Trump would totally kick ass.
Not the same thing as an invitation to throw down. Embarrassing, sure. Totally inappropriate for a fully growed man, sure. Not a challenge to meet after the bell, however.
OMG, look at what he's just tweeted....

Confession to what?
I have no opinion on that.

What does it say?
Remember when they were saying, during the campaign, that Donald Trump is giving great speeches and drawing big crowds, but he is spending much less money and not using social media as well as Crooked Hillary’s large and highly sophisticated staff. Well, not saying that anymore!
It was a well reasoned and insightful response to the role social media should have in our lives.
Let me add that Biden's comment was asinine as well.No, that's not a challenge for a schoolyard fight. It's just the usual taunting of our President, a statement that if they fought, Trump would totally kick ass.

That doesn't mean Trump's response was reasonable for a sitting President, but Biden also shoulda avoided schoolyard taunting.
