I don't dislike her, but she has chosen to make this political. I also think politics need to be kept out of sports, and for that matter, pretty much our everyday lives.
She's had a fairly rough time in her personal life (her brother's problems, primarily) and seems rather angry with life in general at this point. Angry people will lash out at anyone who state opinions which differ with their own. The premise that Trump is anti-gay is not accurate, and I don't even believe that is why she is angry with him. He is outspoken, just like she is, and you've got two personalities who often don't show much judgment or class in their public statements. Both of them feel the need to complain openly about things they don't like and prefer to do it very publicly. Both of them also get crucified to continue to do so, but being the mega egos involved with both of them, they will continue to just that. Finally, both of them are very good at accomplishing their goals. So, in that respect, I admire her and our president for having the courage to do just that. Controversial, historical, and accomplished.
