It’s 100% cool to not care about “rap beef”.
The reason this stuff is in the news is because Kendrick is a very influential artist calling out patterns of child abuse and sexual assault in the industry.
Yes, it all came to light through “diss tracks”, but a lot of the accused behavior has been publicly visible for years and simply ignored.
It’s getting media attention because the world has seen people abuse their fame so many times and we still let it happen. Now a modern artist is emphasizing that the most famous “rapper” is an offender and that the industry has these problems everywhere.
