I learned what being "gay" was. I've always been a bit effeminate, low crying threshold, I didn't enjoy playing soccer with the boys. That was in first or second grade before even being attracted to anyone. They told me it was bad, gross and that the "gays" look just like me. It was the norm to be homophobic in my country. It still mostly is but not as much. This bullshit was repeated over and over until I left middle school. It took me until my late teens to realize I was indeed attracted to everyone.
So long story short the first bigoted people were my classmate kids, the second was myself.
Not sure how much I agree on the dairy part. Apart from the inherent ethical problems associated with it, dairy is an all around promoter of cardiovascular disease. My anecdote is that while I was vegetarian, I suffered from high BP and had to be put on meds. Once I went vegan, my BP dropped to the same levels as with meds before. I'm also prone to gout due to genetics. This change in lifestyle had to be the best step I took for my body.
Now, I see why this study had great results. Eating a varied diet, especially rich in whole foods is a good thing, dairy or no dairy. People just want cheese in their diet and that's a compromise a lot of studies do to reduce dropout rate and make people stick to a diet. It also makes dairy companies happy.
