It’s about the political agenda of “social justice” and “gender equality” instead of just seeking out the most qualified person.
There is no such thing as the most qualified. That is a red hearing.
When was the last SCOTUS from either side the most qualified at the time of nomination?
Again when the last admin said they would nominate a women there was no one speaking out about "gender equality" or "social justice". You don't get to flip flop when it suits your political agenda. That is why we have installed goalposts.
You can put lipstick on a pig but it is still a racist.
