You are fuckin retarded. Oh my god. You know all of this gay shit barely slips past the radar the cartoon networks, right? You either have to beg to allow it like they probably did or, or try your best to sneak past the censors. Remember that trans flag dress from Star Vs. that Disney made them remove?
And maybe you're just forgetting how the government isn't the people making the fucking cartoons. It's creators. And if anti-gay, pro-life creators like Doug TenNapel can still get writing credits on shows with gay kisses like Adventure Time, there's nothing stopping you. I'm not saying "just make it yourself", as if that's an easy thing to do, but it's also not impossible.
And for fuck's sake as a side note if you're gonna whine about liberals forcing their values in media, don't do the same thing yourself when given the reins. Some of that comicgate shit is just as cringeworthy as the New New Warriors. If you want apolitical, make apolitical.
Also I think if Steven Universe made an anti-abortion PSA I'd moreso be wondering who the fuck thought it was a good idea to even talk about abortion to kids. That's not exactly a child-friendly subject.
