The shocking truth is that the US is just one of many, many, many democracies. There’s nothing uniquely American about democracy.
The American system was based on the French implementation, which in turn was based on the British implementation.
What is unique about American democracy is the scale. The biggest issue that America has is that the current incarnation is not fit for purpose - it’s a system that when used like it is, creates massive vote inequality, gives some “elected officials” what amounts to jobs for life and spreads blame so thin that (heaven forbid!) should someone try to create a dictatorship, it would be very hard to stop it.
Ellen - before she was a talk-show host, Ellen DeGeneres played the main character in an Emmy award-winning sitcom. The show had LGBT characters, with Ellen herself (both the character and actress) coming out later in the show’s run.
I’m surprised I’ve not seen Will & Grace mentioned (I’m sure it must be here, but I didn’t notice it). That show famously featured many LGBT characters, including a lesbian couple who were Will and Grace’s main rivals.
Less specifically for lesbian characters, but featuring a gay couple as main characters, you’ve also got The New Normal, a fantastic show about a gay couple that was cancelled after one season, and, of course Modern Family.
I wouldn’t say that this programme was good, but Brookside famously featured the first pre-watershed lesbian kiss on British TV (the watershed is the point, 9pm, where it’s assumed that children will no longer be watching TV). This was in 1994, when we still had backwards Conservative Party laws about it being illegal to “promote public discussion” of homosexuality. For context, it’s worth noting that even two years later, when Carol and Susan got married in Friends they didn’t kiss.
