I didn't vote, because I am completely disillusioned with the American left, but I also do not endorse the republican right.
I think it is a mistake to turn the UFC into a platform for political propaganda. Dana is free to support Trump and they are free to give him free seats, as well as to anyone else they want. And they can and should show him in attendance, as they do with celebrities, and even emphasize his presence, as they have done. But as a company, they represent the fighters, workers and fanbase, and many people involved, including the fighters, might not align with that message or with actively showing a trailer for the guy. Even if a minority is in that position, it generates polarization.
This is selfish and disrespectful to fighters: the company represents not only the will of the owners, but the people that work and compete there. It was a polarizing and needless avowal of Trump.
Leaving freedom for any fighter to express their views is good; making the show a vehicle of support for one side of a very divisive bipartisan political system, is not. I would think the exact same thing regardless of the politician, party, or position.
Flame away...
