How do you counter people who've accepted their own ignorance as bliss? Go and shout yourself hoarse with them in an unnecessary argument on something that should benefit them? That's not me. In the past I used to get bothered about negative comments on Bitcoin until it dawned on me that only trees with delicious fruits get thrown stones at. These people are FUDing on Bitcoin because they've realized the potential in Bitcoin as the beautiful bride with delicious fruits and are trying all they can to shoot it down. Besides, no matter how hard one tries to educate those pessimists it's most likely to end as effort in futility.
