It really has not been debunked, just not conclusively proved.
You apparently won't even accept PBS as a source. Not sure what you would accept. Certainly by now you have found out that even Snopes doesn't debunk it they just post a lot of comment.
I don't accept anything as a source unless it can be documented and/or corroborated. PBS is certainly not immune to error.... just because it's PBS. That's absurd.
The quote is your assertion --- therefore the burden of proof of its authenticity is also yours.
Hardly a debunking of at least part of the quote.
Now ask yourself honestly, what if Trump showed, or allowed to be shown, a screening of a similar film? What would be your reaction?
More about Wilson and racism from PBS. This narrative fits perfectly with the quote:
The Rise and Fall of Jim Crow. A National Struggle . The President | PBS
Don't need it. You're posting to a poster who's been describing Woodrow Wilson as a racist asshole for years here - actually I consider him one of the four worst Presidents since 1900. But that's not the assertion here. The assertion is the quote, for which there's no evidence. As already pointed out the first time it appears anywhere is 1937, and the link of the newspaper image you just posted is fifty years later than that.
Moreover you're still failing to address the question of what the quote would mean if it were real. Why is that?
Is it all about emotion without any rational reasoning behind it? Is that why you're linking these bullshit-infested videos by Whittle Bill with a straight face?
Whittle Bill is a pilot and a talking head in a suit, and a gadfly YouTube attention whore --- not in any way a historian.
