Do you buy electronics? You're actively participating in the funding of wage-slavery and actual slavery in China.
Do you buy from Amazon? You're actively participating in one of the most worker-rights-destructive movements to ever exist in the United States, that the likes of Rockefeller and Carnegie could never have dreamed up.
Do you eat meat? You're actively participating in animal torture.
I'm actually not trying to say that any of the above statements are untrue. I'm pretty in favor of giving Biden grief about Gaza, particularly because it does seem like he's responding to it, a little. "Every other US administration did it" is no excuse, and the bullshit level of opposition he's given Netanyahu so far doesn't excuse the continuing flow of weapons and money all throughout the genocide.
But that said, this "actively participating" to mean Biden's super happy about what's happening in Gaza and affirmatively wants it to continue is very clearly not the way it is, if you think about it for more than 2 seconds.
