Okay folks, time to turn the heat down here, I think.
Everyone is entitled to express their own preferences, but not to question the right of others to express theirs. I'm not sure that's actually what's going on here, but it's worth being a bit careful when you're talking about what others think. And as saying "I don't understand why people x" is a statement and so doesn't invite a response it can come across as a criticism, so if you're genuinely curious and want to understand what others think and why, it is better to politely ask, while being ready to just agree to disagree. And if you're not genuinely curious, it's probably best to avoid talking about others and just stick to expressing your own views.
"You may call it 'nonsense' if you like, but I've heard nonsense, compared with which that would be as sensible as a dictionary!"
