My best friend growing up is a near mystical figure in the insular LD debate community and has coached a lot of nationally successful debaters, including his younger sister who won the TOC and is considered the most dominant LD debater ever as far as I know. Aside from him, at one point another close friend was #1 ranked in the country (he had the most TOC bids that year) and another won Novice Nationals. I was naturally good at it as well (I quit literally hours after winning the Novice state tournament), but I absolutely hated debate for all the reasons listed -- "spreading", abstruse philosophical critiques that always devolved into nuclear war, and the barely intelligible speed-talking that even motivated the dorkiest of debaters to practice circular breathing. I had to find a new friend group (for a while, we're still all close) because these guys talked about nothing except for debate.

I couldn't agree more, and I have said nearly the exact same thing to many people that are unfamiliar with high school debate.
