I don't care about celebrity opinions either and it's more than just her not going to the White House. She was supposed to be representing the US, trying to bring this nation together so we could all celebrate something as a nation. Instead she took her newfound fame and used it to shit all over the US at every chance. It was much more than just not going to the White House, she was another moron kneeling for the anthem, stomping all over the US flag (literally not just figuratively), talked nonstop about politics and the dumb wage gap and demanded more "equal" pay to the men's team.
If you're going to represent the US then just represent the US. Not everything has to be fucking political. I'm just glad her star faded in like a week, she must be wondering where all of the media attention went.
