>>680894>>680900I think making fun of that stuff came back in style in the 00's because
1) There were still people who grew up surrounded by it. Davie and Goliath got reruns for years. It got featured in a Mountain Dew(?) commercial in the 2000, got a special in 2004. It's increasingly less relevant but this era must have been the last time it would be for a large audience.
2) The 00's had a lot of backlash against Bush and republicans and part of that included a lot mocking of conservative Christian ideals. It's arguably why Flanders on the Simpsons became more and more of a caricature of himself by the new millennium
And hell, on that point, lots of these people still grew up in Reagan's US too.
Leave it to Beaver I think it's one of those things that's more known as a symbol of an era than the show itself, so knowing anything about it beyond what it symbolizes isn't required. Family Guy is low brow(term originating from phrenology pseudoscience btw) and yet most of the middle schoolers and frat boys that loved it still wouldn't get half the references. Another thing is, a lot of TV is made by people obsessed with TV, so over referential shit gets made
Now if you're talking about Mr Pickles, I would agree with you. That show came out in the mid 2010's in the Obama era, most people watching had even less of a connection with Leave it to Beaver styled media, it still tried to do the 50's wholesome americana but with a le twist, gratuitous violence and sex that was better in Metalocalypse and SuperJail, that's when it would be cringe to still want to make fun of the 50's.
