Don't tolerate hypocrisy for hypocrisy's sake, but recognize when it's pragmatic to tolerate it to either move things in the correct direction or simply to limit how far they slide in the wrong direction.
But I do agree that there is a case to be made to work those people, if their views align with yours, even though they are personally hypocrites. On the other hand, maybe not the most trustworthy allies.
It's almost inconceivable to me that someone(s) can be both anti-abortion and pro-execution without some deeper, darker, cynical motivator.
Huh. Again, thank you.
I don't think there is a conflict with either position because they are vastly different scenarios, and neither side is basing their argument on an absolute position on the value of all life in all circumstances. A good example would be: Someone who opposes kidnapping, but supports imprisoning criminals. Those positions are not in conflict, even though prison is just legal kidnapping.
My preferred concrete example, simply because of how staggeringly effective tolerating hypocrisy was at getting a resoundingly unpopular law to become the law of the land is American Prohibition. During the lead-up to prohibition in the United States one of the most successful lobbyists was a man named Wayne Wheeler of the Anti-Saloon League. He would work with or endorse any candidate that supported a dry agenda, and he'd work to replace those that didn't with those that did. This included candidates who were, themselves, barely-functional alcoholics. They would drink while meeting with him (he himself was truly a teetotaler as far as we know) while discussing the very legislation that would make acquiring alcohol illegal. He took it all in stride as long as they voted the right way. Despite the perceived success of the wets in attaching a 7-year limit on time-to-ratification for the 18th amendment, it passed the required number of state houses in less than two years.
For a more modern example I direct you to Republican's willingness to re-elect "family values" candidates who support and push through anti-LGBTQ legislation but who have themselves been caught in flagrante delicto. I find such laws reprehensible, but I cannot deny the effectiveness of the right in passing them, in part due to a willingness to tolerate effective but hypocritical legislators.
In terms of where I believe a failure to tolerate hypocrisy has resulted in net loses for progressive causes, I'd point to politicians with strongly progressive voting histories are pilloried and their political careers are summarily executed because they turn out to be corrupt, sexist, racist, homophobic, etc. If their voting history and the legacy they're leaving behind is a progressive one (and stays that way), who cares if they're only pursuing it because they know it will get them re-elected? Unless you can find a candidate who will produce a better net effect, stick with the flawed bigot.
Concretely, take Hillary Clinton after the primaries[0]. I saw it argued that she was a hypocrite for taking millions in speaking fees from big banks while talking about protecting the little guy. She may well be a hypocrite (and her banking voting history isn't great), but the platform she was running on and much of the rest of her voting history are solidly progressive. The number of votes lost due to perceived hypocrisy probably wouldn't have swayed that contest, but more broadly I see it in the same category of being idealistic to a fault.
