What an absolute shame, but kudos to you for bringing some attention to the unfortunate over-touristing of the area. As a Filipino-American who has regretfully never been to Palawan, I'm bummed about this, but hopefully the Filipino government will put measures in place to conserve and protect the area like they did with Boracay.

Disheartening to hear about the bias and prejudice you experienced and witnessed there. Tourist behavior is so often utterly horrifying to the point that I feel like local governments/tourism boards need to work more closely with embassies to keep visitor behavior in check.
