In hip-hop there a right and wrong way to be sincere. It's usually directly tied to delivery and technique. You can only be really "real" if you're a good MC.

Brownsville's Ka is one of the most genuine and sincere rappers out there, talks a lot about being vulnerable and the lowest points of his childhood. He isn't called a cornball because he is a real wordsmith. Chance The Rapper I think did a great artistic work on "Acid Rap" talking about all sorts of heavy stuff, but was rebuffed on "The Big Day" because it lacked any of the technical skill he displayed in previous work. Rather than comparing Ka to Chance (which is just totally unfair now that I think write this out), I think it'd be more better to compare Chance to Kid Cudi.

Cudi has a lot of sadness, depression, sorrow, and weakness in his "Man on the Moon III: The Chosen" album but it's so well done it does not the get ire Chance's got a year prior. Cudi's MOTM3 was this really well put together audio trip, in a similar vein to "Acid Rap". MOTM3 was carried by a vibe, but that vibe I think carried the wordplay and lyrics to a place that had some real emotional impact. "The Big Day" had sort of heartless positivity I think people could easily see through.

Chance's joy wasn't what I think people found corny, I think people just thought it was just bad rap. You can love your wife, if anything most listeners are all for it; but you better have some bars to show it.

I think hip-hop has a lot of room for alternatives to the hyper macho masculinity, but I believe but it demands you be good at being that alternative. If anything I think hip-hop holds those in the alternative space to a slightly higher standard. I don't know if this is a "hot take" exactly, but I feel like a lot people get it twisted that hip-hop is anti-feelings and stuff. It isn't, but it certainly is anti-bad rappers.
