I support your right to declare ignorance! Your defence of it is incorrect.

There is not "literally nothing" you can do to resist genocide in another part of the world.

In this case, there's the opportunity to pressure your legislators into international action. There is the individual personal responsibility to avoid funding the genocide through purchases, and in business as well. Then there are activists who can help one be more effective.

The implication that none of this works is fatalism that is blind to the push and pull of history. Get out and push, if you can. If you can't, then at least learn what you can about why others care so much--before joining the conversation about it.
