Hello Oanta. Nice to meet you.
To me, the fandom's main aspects are RPing, general acceptance of others, and an open-mindedness towards people of different nationalities, orientations, genders, races, age, and the like. Overall, it's just a bunch of typically welcoming people to be around. The use of a fursona, at least in my opinion, is often done as a form of unique expression not possible in any ther way, as every aspect of a fursona, down to it's base physiology, is up for alteration to a person's preferrence.
