This needs to be said
Here's the hard truth for you old heads. You're looking at the wrong issue. The problem is not that rappers are soft nowadays. The real issue you have to confront is that Rap is not the same genre it was in the 80/90s.
Bigger still, America is not the same nation it was during the Golden age.
I'm in my mid 20s.
My generation is doing away with the classic concept of masculinity.
If you go look on reddit and other mainstream sites. They're siding with kanye and turning on Wiz/Amber.
Amber is especially receiving backlash for promoting homophobia and shaming Kanye for his sexual kinks.
In a climate like that i don't see Feminine/softcore rappers going anywhere.
Gen Z is in the midst of a social revolution. For better or worse, my generation is doing away with gender roles, the concepts of masculinity/femininity, and other forms of rigid sexual identification. Instead we are promoting sexual fluidity, "social libertarianism", "free love", moral relativsm, and generally speaking, a society where it is taboo to judge anyone for anything (unless of course it goes against any of the values I named above).
If you feel disconnected now, wait till you see the media campaign for the first major openly gay rapper.
