Hmm, well, consider giving it a go. If nothing else it's an excellent starting point. Many of their articles are to do with massive public misconceptions about major historical events. From there you can simply use google to find further material on sites you find more to your liking.
That site is the reason I know, for example, that North America had a thriving indigenous civilization with a huge population that was somehow decimated not too long before European settlers started showing up. The general idea that most people have is that North America was sparsely populated by savages before the white man came. And that's fairly accurate, but only because the people they encountered were merely the survivors of some cataclysmic event that had destroyed 90% of their society. If it weren't for sheer bad luck (likely a terrible virus) the Europeans would not have found an empty continent ripe for settling with only minimal resistance. And they didn't easily conquer the indigenous people due to any innate superiority of civilized man over savage. They just showed up at the worst possible time from the perspective of the natives. I find this endlessly fascinating and I would never have been set on this path without what is ostensibly an American comedy website but is in reality a brilliant hub for fascinating tidbits.
I apologize for any errors in this post. I'm going purely from memory. You get the idea though.
Also, although much of the content is focussed on the US, it does not take the usual bullshit patriotic approach you may be fearing. A great many of their articles are intended to debunk common patriotic myths that simply aren't true. It really is a gem.
