It's like they have a God-complex. "I don't like this, remove it or else." Even though FN HAS a blacklist so you don't have to see that type of stuff, they feel like they have to "save everyone from seeing it". And yes, some artists actually think like that.

From dumbass artist in the link:
THE ABILITY TO BLOCK IT DOESN'T EASE MY CONSCIENCE.

KNOWING PEOPLE ARE BROWSING THAT SITE TO LOOK AT CHILD PORN, FICTIONAL OR NOT, ONLY ATTEMPTS TO FILL THE DEPRAVED SEXUAL VOID IT WAS DRAWN TO CATER TO, AND IS NOT COOL. IT'S SICK.

IT ENCOURAGES EXPLOITATION AND SEXUAL FETISHIZATION / FANTASIZING OF YOUNG CHILDREN. AGAIN, IT'S SICK. IT DOESN'T MATTER IF IT'S NOT "REAL CHILDREN", THE VISION AND FANTASY IS STILL THE SAME.

News flash: NOT EVERYONE THINKS LIKE YOU. By this stupid logic, what if I say "knowing that people are browsing furry sites to look at furry porn, fictional or not, only attempts to fill the depraved sexual void it was drawn to cater to, and is not cool. It's sick." And some furry artists have the NERVE to say "cub porn will only lead to child molesters". But furry porn won't lead to bestiality and animal abusers, right? Or gun lovers will turn into mass murderers, right? These assumptions are so far off it's literally hilarious. My God, people are idiots. And those SJW's say that they're "open-minded". Hypocrites.

Art is about freedom of expression. No matter what topic it's pertaining to. Many people don't like straight porn, should we ban that too? Many people don't like porn in general, should that also get a ban?
