Someone saw how amazing and loving the Heeler family was and decided "this makes me mad, I'm going to make an intolerant version of this that fits my world view!".
Not to mention I can't remember politics ever even coming up in bluey when I watch it with my kids.
It's one of those fake TikTok "facts" that's only kind of true. The Heelers are blue/orange, which does work decently well with Deuteranopia (red-green color blindness), and is closest to what dogs' vision is like. But it's mostly just a coincidence, and there's plenty of cases where scenes really don't work well if you run them through a Deuteranopia filter, and Chili/Bingo really blend into the background a lot of the time.
I've never heard this before and don't know if it's true or not... but if you told me that Ben Shapiro and his ilk were absolutely furious it, I'd say that sounds a hundred percent on brand for them.
Everyone knows the dad is supposed to come home angry about what he's listened to all day about the left, beat his wife and kids mercilessly to show them who's really in charge, and not engage in any meaningful way with them at all before passing out drunk.
Politics came up. Politics is just a name for any way a group makes decisions. Families are groups and they need to make decisions. Any time a TV show explores the question of "how can a family get along with each other", it's textbook politics.
