You're right, Walkman -- there are already ways for sites that promote unpopular views to get hurt in the rankings. This is one reason why I personally don't think "social engagement" should be a major factor in the ranking algorithm. I just hope that Google will recognize the seriousness of the problem and try to make adjustments to the algorithm that will minimize its effect.
