It's Just Artistic Expression
This got me thinking... You know how people say, "If you wouldn't want your family seeing it, don't post it on the internet"? If my mom saw my Tumblr blog I don't think she'd care all that much. My extended family followed me on Instagram where I'd post all my vent art and anime bullshit. My nonbinary voice-acting cousin, Sydney, also kins Armin. We barely talk to each other, so finding out we both kinned the same character was wild. The Arlert traits are genetic, I suppose.
A few years ago, I randomly stumbled across a DeviantArt account that drew copious amounts of KakaVege softcore porn. I think some of it was mpreg, too. In the captions of nearly all of them, the artist said the pieces were commissioned by her own mother. I told my mom about this in shock, and she replied, "Huh. That's fine. It's just artistic expression."
