She was saying "(if you kick the immigrants out of hollywood), then all you'll have left to watch is football and MMA, which (btw) aren't the arts"
Which is funny because MMA employs a MUCH greater diversity of both foreigners and minorities than hollywood. For that matter, so does football.
She was trying to name things that seemed heavy handed in comparison to acting and her brain came up with things that were literally heavy handed, but her brain didn't finish due diligence to screen the examples and as a result the chosen metaphors don't work as punchlines for her attempted feel good thesis.
She was really trying to be clever. I could tell she was embarrassed because the crowd was a little confused and that's when she knew her joke didn't quite work. It felt like an impromptu joke you might tell at a party and then want to retract it right before the completion when you realize it doesn't work but it's too late so you have to keep going and then you laugh goofily at your own gaffe to cover your ass, which is what she actually did. "Uh- Uhhuhghhh huhhh hhg"
