That's the opposite of what the Supreme Court said.
Yes, a lot of people get this backwards, and it's worth emphasizing that a lot of politicians are looking to score political points by jumping on this bandwagon regardless of what the courts actually said.
But in the end SCOTUS recognized protected classes defined by law and said they must be afforded representation. Any state eliminating such representation is violating the law and the SCOTUS ruling can be used to go after them.
Idiot politicians saying otherwise are... well, racism isn't exactly correlated with intelligence.
