I want to have a word with you. I used to think like you did. But everything changed when I found out my friend is also into this stuff. Then suddenly I don't feel like monster anymore, he has a job, I have a job. Everyone are happy, I don't feel awkward anymore, because I know that if people find out, it is most likely because we are into the same stuff, other that don't want to see it won't get to it.

Drawing violent things doesn't make you a violent person, I think it is other way around, you see what can happen and how scary things can be than people that are not constantly exposed to it. More empathy toward others.
I also doesn't separated my guro work from vanilla work on my Pixiv account, people can actually know who I am, if they try. I don't feel like I have to hide, maybe because of the nature of my work in creative industry, if it is art, even erotic art or ero guro, still I make work of arts, I am not terrorist.
