Andy's "realization" sucked.
This episode is everything you'd expect from a leftist All In The Family type "I get my ideological way" episode. Andy ranted about them "socializing" his barn, talking about it as a witch's coven, calling them hippies, mentioning he spent all his time on the radio idolizing family values while flying around in the atmosphere being a sexless loner. Ranting about illegal immigrants, being a Pro American.
I like Andy, but as far as the narrative of the show goes, he's "wrong with a heart of gold." He just needs to be shown the light and given love and tolerance and he'll "come around" to their way of thinking. His realization and resolution characterized why he felt that way and how he came to those conclusions as just "being afraid of change" and "tradition and what he knows being threatened."
Okay, imagine a fat girl wrote a story about skinny girls. She put a skinny girl in the story. The skinny girl went on a rant about fat girls and ranted about why she hated them in this story. The fat author then has the skinny girl admit she was just jealous of the fat girl because fat girls are beautiful and noble and totally not smelly, and she's jealous because she's skinny.
That's effectively how Andy is written when it comes to his conflicts and character. But personality-wise, he's a cool guy. He just needs to be The Conservative Put In His Place for the show.
Given how Rebecca Sugar is openly an intersectional feminist, and intersectional feminism draws from Critical Theory (which itself is drawn from marxist literature about the bourgesoise and proletariat, how the majority inherently oppresses the minority, how the minority must be given things until they're at parity in numbers to the majority) the digs mentioned about Lapis and Peridot not respecting personal property and "socializing his barn" were not accidents or mistakes.
