"I hate all of these facts and wish they were not true, which makes me a credible source for them."
I was going to say that the only reason for hating the first was that you were an ethical vegan. But I realize that the more likely reason is because you dislike the field being an example of confused and misleading science and many people so mislead acting counterproductively, in good faith but to no avail.
I hate that too.
Information that surprises you is interesting as it exposes where you have been miscalibrated, and allows you to correct for that.
I suspect the users of LessWrong have fairly similar beliefs, so it is probable that information that has surprised you would surprise others here, so it would be useful for them if you shared them.
Example: In a discussion with a friend recently I realised I had massively miscalibrated on the percentage of the UK population who shared my beliefs on certain subjects, in general the population was far more conservative than I had expected.
In retrospect I was assuming my own personal experience was more representative than it was, even when attempting to correct for that.
