For what I would not put in or do in my comic will vary in what the story needs, as long as it's within my personal moral standards.
I'm not 100% against depicting nudity. As long as its celebration of human beauty, rather than exploiting the reader's feelings. Women are beautiful to me, so I sketch them more than men. I find their form so much more interesting than men. However, I would never draw something that couldn't show my parents or my children, mostly because I fall in that category in taste. I am very timid when it comes to sexual themes, so it would be difficult for me to truly depict it the way I would like to see it properly.
So in a sense, I am against vulgarity. Anything vulgar I'll avoid drawing or depicting. I've drawn blood, but that's as close as it's going to get. Violence has its place in an action comic, but brutal mutilation or overdone amounts of violence are not my forte.
I will not have my characters swear. I don't, so I won't have them do it. I might allow some grawlix, but otherwise I wouldn't write anything I wouldn't say aloud.
