Let's do a quick comparison. If me and my ancestor were in the same room and I introduced him to this game, would he understand? Would he even care about a cartoon porn game? No. It's not even real, and there's nothing disgraceful about playing a game created with sketches. Let's say I told him I was "gay". Would he understand? Of course he would because people like that existed during his time and others found it disgraceful.
Now that you're into your right mind, would my ancestor kill me for playing something he doesn't understand? Of course not. Would yours kill YOU if you were "gay"? Definitely.
