I'm not. How many other groups could have been chosen for this? Why Hamilton? It is IN YOUR FACE and I don't have to have a bunch if gay singers forced upon my TV screen chosen from thousands of "normal" singing groups. To hell with the Super Bowl and the politically progressive NFL. Lady GaGa was bad enough, this ices it for me.
There was such a public thing made out of their disrespecting VP Pence, that their mere appearance is already a statement, even if they say nothing at this event. Sort of like if Hitler appeared at some event and had good manners and didn’t outright say anything anti-Jewish - still, just his invite would “speak” even in silence. It is a huge middle finger whether they say anything or not at this point. Consider all the performers that were threatened with death if they innocently consented to perform at the inauguration.
