For myself it's just a hobby. Although I have a fursuit of my own, I don't wear it often and mostly just wanted one for photoshoots or to cuddle my friends, haha.
I'm not super active in the fandom and to be honest I'm not very open about being in the fandom. I really like the art and I joined it because I thought of having an anthropomorphic animal that looks like you to be an interesting concept.
On the other hand, I know people in the fandom who see it as a lifestyle. All their clothing is furry themed, they have furry art all over their room/house/car, they only date/associate with other furries, and the fandom is one of the only things they talk about.
That being said, overall it is a pretty good community and I like it for what it is. People for the most part really care about each other and I have witnessed members of it go above and beyond to help each other. I have met some great people through the fandom, but the only issue I have is that there is no accountability and a lot of people in the fandom don't really take care of themselves. (In terms of their appearance.)
