>I'm a bit taken aback by the community built around it.
That's good intuition. I'd recommend staying outside of the fandom.
>Is e621 the best place to find furry porn?
It's not the best, but it works. You'll probably want to pull material from a lot of different sources anyway (pixiv, furaffinity, deviantart, etc...), and to that end, I'd shill Hydrus for organizing all of you images.
>Is there any good place for furry comics?
There's quite a few netlabels for comics and whatnot out there. Some even distribute physical copies too, although the only one that comes to mind right now is Rabbit Valley.
>How important is having a fursona?
Not at all important.
>When interacting with furries elsewhere, I've found that I get a lot of flak for not being into certain kinks like hyper, scat, and diapers; is that common?
Try finding furries that aren't in the fandom solely for fetish material. And yes, it's possible.
>Is there a decent furry ERP community, or is it cancerous?
If there is one, it's probably cancerous. Most people will recommend F-list, so lurk around there a bit and see if there's anything you like.

Are you replying to the right person?

Why such a strict definition? Is feral art not furry?
