Moral responsiblility

Once I become aware of an issue, I will not ignore it, although I frequently do not deal with it in the way that most people do. For example, the issue of slaughter houses in the US would cause a lot of people to become vegetarians. I would, instead, write a protest letter to the company, but I would continue to eat meat. Becoming a vegetarian would accomplish absolutely nothing, in my opinion. But many people still do it. And accomplish, what, exactly? The animals still die, in the same way. Their protest falls on deaf ears, simply because the protestors talk to the people that perpetrate the act they are protesting. Still, I think that all people are morally responsible to at least attempt to affect the issue in question, though I personally think that it should be in a direct manner, rather than some vague and subtle approach.
