Duh, they're union members - they get outstanding benefits from the union and should do their duty to it and their co-workers, or get out. Nothing at all wrong with that. They aren't there to prevent people from voting. They aren't espousing racism in a chickensh*t format.
Unions are WHY we even HAD a middle class (once) in the first place. Too bad rightest lamers managed to convince everyone otherwise by appealing to their elitism ("I'm better than they are") or greed ("I deserve more than they do!").
You can't compare unions, whose goal is worker protection from wage slavery, to rightist collectivist mobs, whose goal is a homogeneous, thoughtless society of dutiful non-reading non-thinking TV-slurping narcissist drones.
