I think most queer people who care about representation would say: shows are doing more now and that makes the current decade better. the same goes for disabled people. and while the 90s felt like black shows were gaining traction, I think the 2010s were better than the 2000s.

I like many old shows, but I don't think anyone who cares about marginalized people and characters will pick an earlier era: it's slowly getting better, it still needs to get much better, and the current savings/cuts might be the sign that 2017, 2019 etc. were a high point (that wasn't even that "high").
