I used your exact argument on you (except I was using the 99%+ of athletes as my example and you were using the 0.1%) and then you say they aren’t dietitians or doctors lol. Is Chara one?
You should probably actually look into which athletes are mostly or near 100% plant based. Give it a google search and you may be surprised.
Venus Williams, Cam Newton, Novak Djokovic (who is literally ranked number 1 in the world), Tom Brady (he's like 80% plant based 20% meat), etc.
It's very common among rock climbers, iron man competitors, cyclists, etc.
We are omnivores and have evolved to eat meat. I wouldn't give it up personally - I'm eating grilled chicken in a salad as I type this. But if you get all of the same amount of calories, nutrients, and vitamins from plants + supplements, there isn't much difference from an athletic perspective.
I went vegan for a few months a few years ago and it didn't negatively impact my performance at the gym during that stretch. It's just when people attack vegans and say "you NEED meat" I find it very obnoxious since it's clearly not true for everyone and plenty of people out there have competed at the highest levels of sports without eating meat.
If you stop eating it, it's not like your body implodes. Especially if you're a pro athlete who knows how to supplement/get all the necessary nutrients.
Personally, I prefer more of a Mediterranean diet for my fitness goals.
