In 2023, most people are "corny" if we're defining corny as being a non-thug or a non-street dude.
The majority of Black men who get married aren't thugs. The majority of Black fathers aren't thugs. The majority of Black men in long term relationships aren't thugs. And Black men have the 2nd lowest interracial marriage rate after White men even in the upper classes where 80%+ of Black men have Black wives.
I'm "corny". You're "corny." Drake is "corny." Kendrick is "corny." Idris Elba is "corny." TD Jakes is "corny." Lebron James is "corny." Etc. That's because "corny" is subjective and anyone is capable of getting hit with that label by any random person.
That doesn't automatically mean that you can't get laid, can't get a girlfriend, can't find a spouse, can't have a child, etc. in the Black community. It all depends on the company you keep. If you're hanging out with thugs, hoodrats, baby mamas, IG thots, and drug dealers all day who only value Black men who are in and out of jail or don't work a regular job, then that says more about you than anything else.
I only hang out with Black folks who share my interests whether it'd be deemed "corny" or not.
In reality, being super short, ugly, and socially awkward is a much bigger death sentence for a Black man(or any man) than being "corny." Drake is "corny" and he was a lot of young Black women's favorite rapper at least before the Megan diss.
