Eh I kinda was by proxy. So, three separate points here:
1. How is Changed being advertised to kids? I haven't even seen an ad for it before. It's clearly marked as having mature themes on steam.
2. Something can be both a kink and art. Those aren't exclusive.
3. How is it harmful? I don't see how this could hurt people (that are the appropriate age) in any way. Would love your reasoning.
As per your final statement, I wish people wouldn't treat NSFW content as inherently worse than SFW stuff.
