Hentai is artistic freedom. People should be able to draw what they want, no matter what the fuck it is. If their art offends someone, then the offended person needs to GROW THE FUCK UP and GET THE FUCK OVER IT. I don't care how sick or twisted the artist is that has the most fucked-up fetish in the world, if it makes them fucking happy, then let them fucking draw it. I've seen so much fucked up shit on the internet that was "out of my league" and I am so used to it that it doesn't even bother me anymore. Critics are simply bigoted assholes unless the person they're criticizing is abusing real-life human or animal rights. Otherwise it's fine because what's happening in the drawing is not happening in real life.
