Chinese one child policy is enforced only in coastal Chinese cities. Even there, if one or both parents of the couple was an only child, the couple can have 2 kids.
So one child policy is enforced only on 1/3 of Chinese population. Most Chinese can have 2 or more kids.
Also, if racism and hypocrisy are the real issues, then Whites are the real victims here.
After adding all the White Births there are only 7 million white babies born out of 135 million non-white globally.
So extermination of Whites seems to be the real agenda here, not carbon or resources or climate.
