I'm wondering if a lot of that is just playing up the reactions for our own amusement. I'm not saying everyone who has a Kiwi Farms® brand account needs to immediately go out and desensitize themselves to all the gross shit the internet has to offer, but there are new people joining the internet every day, so chances are you could run into someone who somehow hasn't seen goatse or whatever. Either way, this isn't the first furry, cartoon sperg, or rape fetishist we've encountered on this site alone - including all of those in the same person - which is why I think some people are just 'punching up' their reactions.
