zxcvcxz could have been a bit more civil about it, but "You seem rather high on the moral horse for someone hosting child/underage porn." is a kind of personal attack as well. You're right about "stooping to their level," though; it would have been better if zxcvcz had made their intent clear with an addition like "see how easy it is to make uncharitable assumptions about people?" in the original post.
And while zodiakzz may not have made any explicit statements about wanting to enforce limits on freedom of speech, it's a fairly safe assumption to make of the kind of people that feel the need to follow Fredrick around all over the internet, posting uninformed slander, reporting him to payment and crowdfunding services, and/or (topically) using botnets to DDoS his site. Hint: They don't care about similar or worse content being hosted on other user generated content sites, it's all about getting back at him for providing hosting to maligned groups like GamerGate, and killing intelligent discussion or attempts at reconciliation before they can happen by derailing threads.
