If I understood the article correctly, there was a report on past slavery and colonialism links to NT properties published on the website. I'm not sure that I would consider this a barrier to people enjoying an outing at such a property.
In reality probably not no, but the reporting around everything has been somewhat histerical.
Yeah, I think you have to actively engage the 'system 2' analysis part of your brain when reading media stuff, and consciously try to extract the facts from the outrage and triggering, even from traditionally 'reliable' sources. It's kind of hard work but otherwise you just get manipulated too much.
