I agree that they shouldn't have to make excuses.

There are people out there who are persuadable but currently buy the Republican anti union bullshit, though. For better or worse, one way to crack through that wall is to point out the ways that unions and collective action like strikes leads to better outcomes for every worker (not only union members), and every worker's child.

I'm aware there's some pseudo science danger, but if the membership is informed and can vote their conscience individually, I'm sure they'd do better than not most every time. Obviously if there's a pressure campaign or film flam man at the top lying or misleading it can all go to shit.
