I know that's meant to be tongue-in-cheek, but my take on that would be that while nobody can be criticized for saying that they simply enjoy something, that doesn't mean that all valid opinions can or should ideally translate into or be reduced to expressions of enjoyment. Personally, I would absolutely hate for this place to be transformed into that kind of environment/adopt that philosophy. Even just as a reader of this forum, I have no use for finding out what people merely enjoy, I mostly just care about what they admire/appreciate/think is valuable/feel strongly and opinionated about.
While obviously there's no need to get personal or cross any lines, I think ideally, toes SHOULD be stepped on, actual opinions SHOULD be argued, and we should have thicker skin about those perceived differences (and take them with whatever grain of salt we think they're worth) instead of walking on eggshells and keeping everything strictly about individual preferences. Often, you have those preferences in the first place because there's some part of you that sees more arguable and impartable/transferrable value in them. Even if it isn't technically measurable or provable, my primary interest here is that I ideally want people to try to express the truths that they personally see. And honestly, where I might differ from what Violenza Domestica said is that I want that attempt regardless of whether or not they're able to back it up.
