I don’t think the alternative is “difficult” for its own sake. Rather, those who would use the term as a pejorative are likely seeking new experiences and viewpoints in their music and get bored by same old diatonic melodies over plain inoffensive grooves. Novelty is a source of dopamine for some.
A lot of jazz music is difficult to the untrained ear, and I have distinct memories of hearing albums that I now feel are too conservative but in my youth thought they were too chaotic. I now understand that it was never difficult from the performer’s perspective - just high level musicians playing the music they hear. I wish everyone could hear jazz just once through the ears of a jazz musician.
In the United States, you can get in trouble if you recklessly leave around or provide alcohol/guns/cigarettes for a minor to start using, yet somehow, the same social responsibility seems thrown out the window for parents and the web.
Yes, children are clever - I was one once. If you want to actually protect children and not create the surveillance state nightmare scenario we all know is going to happen (using protecting children as the guise, which is ironic, because often these systems are completely ineffective at doing so anyway) - then give parents strong monitoring and restriction tools and empower them to protect their children. They are in a much better and informed position to do so than a creepy surveillance nanny state.
That is, after all, the primary responsibility of a parent to begin with.
