Whatever generation you are in also has people in power who are fucking the planet. Are you responsible for them? No.
There are many many boomers who put up a good fight and are still putting up a good fight. We need solidarity with all people who are not those who are destroying the planet. These reductive “boomers did it” memes ignores the reality that a very small cohort of people are destroying the world. And they all benefit when anger is directed at people who are powerless.
