What bugs people, me included, is very different. It is the forced inclusion of diversity seemingly everywhere. It is the constant subtle messages of "white man evil" in shows where it doesn't add to the plot. It is stuff like the Oscars being explicit about requiring minority leads. It is the one sided diversity where blacks, browns and Muslims are protected but it is perfectly acceptable to make racist jokes about white people or say Christians. It is the subtle shaming of anything conservative.
FYI I am mixed race, liberal, and not Christian. I am also of child rearing age and don't like seeing my kids being indoctrinated at so many levels.
It's nice that you're a mixed race liberal Christian who has kids, but please answer the question. It really is coming across as a bunch of people who want way too much to be angry about something without knowing precisely what it is they're angry about.
Also, apparently it's annoying to "force" representation in shows but it's perfectly fine to have shows whose literal only purpose is to drive demand for various dolls and toys. As if anyone would have created Bob the Builder or whatever without a plan for selling it in Walmart.
The fact that the inclusion of LGBT and/or PoC in a children's program is at all controversial tells me we still have a problem that needs to be addressed. If you really don't like the idea of seeing a black or gay person on TV then you are the problem.
The sad thing is that a big majority of people complaining are people who are past child-rearing age and thus not even the target market for any of these shows.
