The only time Biden would have wanted to meet Trump in the neighborhood was when Biden was 10 and Trump was 6. That’s because Biden’s a bully. He’s only a tough guy when he takes on people who are smaller and weaker than him.
Notice how tough he has gotten when he's surrounded by his secret service detail. He knows that they're professional enough that they would stop any threat long before it got to Brandon. Of course, he's deluded enough to think that they also do that because they like him. Personally, I think that they would love to stand aside for a few minutes while he got his ass thoroughly kicked before they slowly break it up. Particularly, any of them bitten by either of Brandon's untrained and apparently mean German Shepherds. It seems that no one in the Biden Family was very concerned about their dogs' behavior.
