Eh. I'd agree they're largely cool. But then they're practically eugenisists when it comes to Rory and Lorelai's partners. They intentionally bombed Lorelai's relationship with Luke, a stable, kind, generous, and successful small business owner because he didn't come from wealth. They also refuse to believe that Logan or his family was anything but perfect until his father fully admitted it. To their credit, Richard had to step away before he got physical with him and Emily let Logan's mom have it in the most Emily way possible. But they were prepared to assume that their quality as people was equal to the size of their bank account despite being told by Lorelai exactly how awful they had been to Rory. They were prepared to deem Lorelai a liar and not believe a word of it rather than consider the possibility that the Huntzberger name didn't mean that they were implicitly great people. They value money and status over everything, even their own family, on a number of occasions. And the irony that Richard's mother hated Emily and didn't support their marriage because of Emily's family is completely lost on her too.
