Yeah it says that and guess what, women weren't really considered "people" hence the reason WE DIDN'T GIVE THEM THE REASON TO VOTE. In CONTEXT of the 14th passing, it had nothing to do with women and was solely for men. Because of that, it cannot be interpreted to be for women that would just be wrong. That's like saying the word for wheel in chinese doesn't mean wheel in english. it just doesn't compute
So the court's interpretation improves. That's a good thing.
Women weren't granted the right to vote under the 14th, but they should have been.
It took over 100 years for the 14th to say gays have equal rights in the military too - until a federal judge ruled this in the last year - but he did and that's a good thing.
It's the older, bigoted interpretations that are wrong. It's the wrong interpretation that looks at the language "nor deny to any person within its jurisdiction the equal protection of the laws." and says, "oh that doesn't mean the laws about voting for women." Society 'wasn't ready', but it was wrong when it wasn't.
The Supreme Court rules segregation was fine in Plessy v. Ferguson, and 60 years later said the 14th meant it's not constitutional, and that was a good change.
Sorry, people who get basic logic but not the larger issues, but sometimes the court is wrong, and legal understanding and societal understanding evolve.
It didn't change or damage or negate the constitution for gays to start being covered - it corrected and strengthened the constitution that was erroneously interpreted before.
It didn't open up the gate to 'the words don't mean anything but the arbitrary opinions of the justices' - there has been a lot of improvement more than worsening.
It didn't suddenly mean 'your dog can vote' or 'you can marry your car'. That's ignorant idiocy, and used to persuade idiots to oppose the good improvements.
The very function of the court was modified the right to interpret was interpreted.
The constitution gave the right to interpret sort of, but didn't say what to do if it found a law unconstitutional, and some founders didn't think the court could strike down a law. What it was supposed to do, I don't know. Apparently state its opinion and let the other branches do what they wanted. But they interpreted the constitution to give it the right to strike down laws.
Interpreting the 'spirit of the constitution' is essential to protecting the rights it's intended to protect, and Scalia's radical opinion undermines the constitution.
