it's interesting to see the summaries become more inaccurate and incendiary as you change the "bias" from left to right.

left wing summary:

• The 4B movement began in South Korea in 2019, advocating against heterosexual marriage, childbirth, dating, and sexual relationships with men.
• Supporters aim to boycott a system they believe promotes gender inequity, seeking control over their lives.
• The movement's potential expansion to the U.S. Is seen as a response to perceived threats to women's rights following an election.

right wing summary:

• A group of American liberal women launched the "4B Movement" to boycott relationships with men who voted for Donald Trump in the 2020 election.
• The movement is a protest against perceived threats to women's rights, including concerns about abortion rights and gender equality.
• The effectiveness of the "4B Movement" in causing political change is currently uncertain, as it primarily aims to make a statement.

notice how the left wing summary properly states that this is a movement that started years ago in korea, and that it's something that women in the US are adopting due to the recent election. meanwhile, the right wing summary falsely claims that the movement was created by "American liberal women". it also claims that the movement was created to "boycott relationships with men who voted for Donald Trump", which is just not true from the other things i've read. everything else seems to indicate that the 4B movement is about boycotting relationships with all men, not just trump supporters. but maybe i'm wrong about that last point.
