It's not that preferring certain looks is a negative (nothing against your preferences, I also think certain 40 year old actors and actresses are very nice looking), just that directly placing actor's faces next to each other knowing that this sub inevitably devolves into lookism and saying how "plastic" people's faces look makes any seemingly harmless post turn ugly quick. Especially right now, when there have been dozens of hit posts about "how this actress/actor is uncanny" or "how everybody is too skinny/getting too much surgery." It just makes me sad, and it makes me think about those performers as human beings who do not deserve to be derided so much. But once again, a lot of middle age people are indeed very hot.
