I'm liking you more and more. xDThe people who expect a group to agree with them just because they share an interest are usually the people who are the least educated and/or open minded on a given topic since they rely on others to tell them what to do, where to go, and who to sleep with at night.
In short: I agree. It's foolish to base your morals or values on a group. That isn't a community. It's a Cult. Confusing the two can be rather dangerous sometimes.
That said, I do think that Furries can form an overarching group or "community" at conventions and in forums such as this. Especially when a goal is perceived, such as raising money for a shelter or helping FA stay up through donations.
There is not an inherent evil associated with the term community for me, but that's because I define it as what it is, and not what people can associate with.
I don't find the term evil or negative either, and it have its uses for sure, though it should be applied when it actually fits. I prefer to use correct definitions and words to describe something so as to leave as little room for miscommunication and/or misunderstanding as possible. Words are the only things we have for communicating with one another after all, and as such it's important to use direct and distinct language to convey one's thoughts and emotions properly.
