I got a Spectre TV (pretty cheap, they sell it at Walmart). It's a little more expensive than other TVs in the same class, but has no smart features: you plug HDMI into it and it displays it. You hit "Source" and are greeted with a no-nonsense menu that lets you choose the HDMI port, composite input, etc. It's great.
It sucks that this happened; some people can really be scumbags.
However, I'm really not sure that there is a solution to this. People in general are racist/biased/sexist/thing-ist, all over the world. Trying to regulate that fact doesn't make sense (how would you even police that?), but perhaps confronting her about it could help. If you sent her your blog post, detailing the steps that you took, she could come around and tell you a more reasonable explanation, like that her schedule is unstable and she had lots of other offers.
