Why people get offended about the "inaccuracy" of Pocahontas

I keep seeing this question over and over, and no one (that I have seen, anyway; apologies if I've inadvertently missed it) has actually answered it except to defend the use of racist, historically inaccurate propaganda. I'll give the short version, with the caveat that this isn't meant to preach but to educate.

'Pocahontas' (real name Matoaka; 'Pocahontas' was a nickname given to her) was 10 or 11 when she saved John Smith's life. That was it. He omitted the part that his life was spared; in fact, until her death he didn't mention meeting her at all. At the age of 17, she was kidnapped by another British colonist, John Rolfe, and held for a year against her will. Some not very nice things happened to her during this time, and at the end of one year the condition of her release was that she marry her captor, so she did, and her name became Rebecca Rolfe. Exploitation and forced marriage, not that romantic and certainly not that entertaining either. She went back to Europe at some point with her captor, was used in propaganda to 'sell' the idea of colonizing 'America', and actually did run into John Smith again there; she was furious with him, refused to acknowledge him the first time and showed him the door on another occasion. She died on the way back to 'America' and was buried there. This all happened by the time she was 21. Once they'd returned they proceeded to wipe out most of her people and scatter the rest of them, these being the same people who helped them originally, showed mercy to someone (John Smith) who likely, according to accounts from his own men, deserved a cruel fate, and shared resources with the people who were colonizing them.

The Powhatan Nation - the people who Matoaka descended from - offered to help Disney make the movie historically correct, but he wasn't interested; he wanted something that was 'entertaining', 'harmless', that would further the generally accepted romanticized version of the story. There is nothing about this story that deserves to be romanticized, trivialized, or made into entertainment of any sort unless they're making a historically accurate biopic or documentary and people are watching it to learn the truth, which let's face it, rarely if ever happens in the movies. Disney could've stuck to depicting animals, creating fictional beings, doing something actually creative and original that didn't rely on tired stereotypes and whitewashing but he didn't, despite the fact that he knew the harm he'd be causing and the misinformation he'd be spreading. It's not just that it's inaccurate; it's that it exploits an entire group of people and renders their struggle obsolete, and then people will fail to see or to understand the problem because it was created under the Disney banner and so, of course, it must be harmless.

It's offensive because it erases the genocide of a people in the colonization of what is now known as America. It fobs off the violation of lands and bodies as entertainment, centring it around a fictional love story to make it more palatable. And then it's spoon-fed to children who, as someone else pointed out in another thread, aren't always aware enough to question what they're watching, and the cycle of racism and ignorance continues. The reason why stories like this are problematic is that they keeps the truth hidden, which, as we're all learning today, is the most dangerous thing of all. So, y'know, anyone who gets offended by killjoys, historians, and people who get offended about the whitewashing of genocide will probably get offended by this post too. That's okay. Feel what you need to feel. Have that instant angry reaction, or whatever your reaction may be. But then hopefully you'll get honest with yourself about why you feel the need to hold on so tightly to this kind of 'entertainment' when you can enjoy many (millions, in fact) of other stories which do not trivialize and justify the decimation and exploitation of people, and take the time to also consider whether that's really the kind of legacy you want to leave with your children.
