Morning! :)
Seems like we are shifting the problem here. I agree there are disrespectful folks who complain, offend the other and don't get the point of preferences, but it doesn't necessarily mean it's done only by minors.
Also, I agree that it would be better to choose content appropriate for you age. But. There are people who are mature at an early age and it's not like you have to be traumatized at 15 when you see someone making out, you know? Strong language you hear even on the streets. There are much worse things some unfortunate souls have to experience like drug use or prostitution. And with internet available to anyone nowadays you can have access to things worse than smutty bl. Yeah so let's not Interfere with their choices, not like our opinion matters to them anyway
