Once we're discussing that, we're just discussing language, not the topic at hand.
That's somewhat necessary; there is a difference between a qualitative evaluation of something, and a quantitative evaluation, especially when the evaluation is comparative in nature.
The size or structure of something has a metric that can be objectively stated, regardless of comparing it to something else. By contrast, how "nasty" some person or group is or is not has no quantitative aspect to it, only a qualitative one; ergo, trying to answer a question about it - especially when a primary method of evaluation is via comparison to others (e.g. you mentioned football fans in your initial post) - is going to involve a discussion about what the language used is intended to mean.
This isn't "dismissing the validity" of adjectives; rather, it's a rejection of the dismissal of relativism. If you're going to posit that comparisons don't matter in considering this question - presumably because there's an objective criteria for what constitutes nastiness - then it'd behoove you to outline said criteria (ideally in your initial post) and ask if anyone can point to an instance of it in this community. If so, then the answer to the question in the thread title is "yes," and if not then the answer is "no," and there's no need for further discussion...at least not based on the criteria you're using.
