First of all that’s not likely correct info. I can’t see the uncited chart you posted but it certainly sounds untrustworthy

Because its results disagree with your opinion? I'm not sure what constructive can come in any discussion after a line like that.

I’ve seen several charts in documentaries and research papers and they generally show roughly the same pattern, comparable to this chart.

So evidence that concludes anything other than "everyone has to stop eating meat now" is immediately untrustworthy. Understood.

But let’s say someone managed to convincingly cherry-pick some corner-case legumes that are bizarre outliers to the overall pattern

Let's say someone made the brash presupposition that the only way to show eating meat isn't destroying the environment is cherry-picking corner cases.

Not a fan of Ronald Regan but there is a useful quote by him:

“if you’re explaining, you’re losing.”

IOW, you’ve added counter-productive complexity to the equation

I agree with your statement about as much as I agree with Ronald Reagan. Like many Republicans, he was a fan of the tactic of oversimplifying an issue until it was easy enough to pretend to fix it with a trivial solution. Economy? Trickle-down! Anything more than saying "trickle-down" is adding counter-productive completixy to the equation.

The problem here, specifically, is that there are more farmers in the US than vegans in the US. You might have a point in that many farmers are already working towards improving the environment and most vegans tend to have such a shallow view of the issue that you need to reconcile veganism with the environment to get them to help the environment. But in the process you're losing environmentally conscious educated people who are in a position to take action, which most vegans are not.

This is not an environmental activist move. It’s the move of a falsely positioned meat-eating climate denier strategically posturing.

And here is the problem. You just did it. You just told me I'm not allwoed to be an environmental activist because I support ethical meat-eating. Another guy (well I assume it's someone else) was attacking UC Davis, a reputable college.
