Same here. There's a big difference between not understanding how anyone can come to a certain conclusion, and saying nobody's allowed to come to that conclusion, or even that this conclusion is wrong.

It actually shares some shocking similarities to a statement made by a relative one year around Christmas. They live in one of those neighborhoods where the neighbors all try to outdo one another decoration-wise. Every year, the house across the street had miles of blinking, gaudy lights, a herd of animatronic deer, an inflatable Santa, and Christmas music playing on outdoor speakers. But this year, they also had, for some reason, lawn flamingos. My relative said "I can't believe they have flamingos. How tacky!" Now, I'm not saying they aren't entitled to their opinion, and that it all isn't subjective anyway, and that I didn't ultimately agree with them that the lawn flamingos were in fact tacky, but nevertheless, I doubt I'll ever be able to understand why those flamingos, of all things, were the tipping point. It is pretty much the same feeling I have for all the rage over Vader's "Nooo!"
