I'm sorry but you're just missing the point. You're taking the term literally, but it is very simple in practical terms how this actually plays out:

diverse is code word for non straight White male. Slightly more diverse would be straight White female.

Obviously OP is simply saying, as a White man, he worries his children through no fault of their own by virtue of birth would be excluded or limited by these cultural trends.

Blame on their kid? What sense does this make? He's blaming the system.
