I've watched Charlie Kirk debate. He's an absolutely awful debater.
First off, he chooses his opponents. He's going up against college students, often unprepared ones. He never goes up against people with experience.
Secondly, he's the absolute KING of gish galloping [0]. If someone ever actually starts getting an upper-hand, he just resorts to spewing a non-stop tirade of bullshit. He'll ask 10 questions and then interrupt them after they've only answered one, just to go off on more bullshit. The problem is, people who don't know shit about debate thinks that's winning.
So yes, his style hurts the national dialogue.
