you can support them directly, or via a less morally bankrupt middleman. not supporting a company who supports something doesn't mean you are against what it supports, but supporting one that does support something means that you either support what they do, or consider your own convenience more important than standing up for what you really believe in, which means you may as well not fucking believe in it in the first place.
as for it being 'not my moral responsibility', well... we've seen what happens over and over in history when someone decides not to speak up simply because it's not them being persecuted. it's a despicably selfish attitude, though given your posting history, i'm not surprised. typical 'fuck you, got mine'.
