@tk You can't take responsibility for every part of the chain of everything you use. But you can chose to stop giving money to one of the most dangerous people alive directly. Or at least reduce it.
And I'm not saying this is your intention, but I have seen this argument used as a "you can't do anything, so you might as well not even try" when I've posted about this before, and that is insane to me. And dangerous and bad.
