This 4B "Movement" is yet another contrived and propagated campaign to meet Eugenic depopulation goals. Gender confusion, identity confusion, birth-control, abortion and the imposition of contrived homosexuality to advance a long-standing agenda that has been in the works for decades is full in play. This is ages old military strategy that has as it's heart the attritional reduction of an opposing force. The manner in which this is conducted in modern times is with PSYOP (Psychological Operations). PSYOP is the most effective and dangerous weapon ever conceived because it strikes at people's cores. It manipulates perceptions, rewires people's thoughts and directs them like shepherds leading livestock to awaiting pens.
People have this idea that these movements are organic and originate laterally or at the grassroots level. Nothing could be further from the truth as much like "Climate Change" and divisive terms like "Boomer", "Millennial" and such, they originate from the enemies of humanity. If you mind what you consume nutritionally, the same care needs to be given to what is consumed and digested mentally.
This sounds outlandish but it makes more sense than anything else I've heard.
Cheers, once you've researched the history and end goals of global Eugenics and covert-strategic depopulation warfare you'll learn this tracks and has been set on diabolical course.
