as someone who used to draw vent art as a stupid kid and was eventually lectured by my parent to not do that, yea, it's for the better if autumn's sister corrects her kid. majority of the time vent art from furries or kids isn't some provoking think piece autumn, most of the time its just them drawing edgy monsters/creatures saying how much they want to kill themselves or drawing highly violent and inappropriate pieces. from a parents perspective, that's probably really concerning and alarming, especially if their kids have never showed any other signs of that beforehand. and if parents never lecture and teach their kids on how to properly express and talk to people about their problems, most of the time these kids end up falling into rabbit holes, just look at other cows like birdie and kittydog. or hell, even autumn herself, since she's always venting to the internet.
