By 'illegal things', which crimes are you talking about? For accidental crimes, everyone and their mom has commited them. For punishable crimes, I accept that crime does exist though not as much as 'most'. For felonies, as far as I'm aware, only one of these two groups have had the FBI banging on their door.
Additionally, an anti-furry suffocated a hotel guest and hospitalized 19 others during a convention shy of a half-decade ago.
As for NSFW, we are perfectly fine due to rule 34 of the internet.
