This has been my complaint. Democrats have been wanting to display honor but they're doing it emotionally based on their opposition to Trump; that they refuse to stand for someone of his persona. It's easy to do such thing when you're already powerless at every level right now, and when one more loss wouldn't be as damaging for them as it would be for Republicans.
Let's just say for the sake of argument that Democrats are more honorable.
Showing an example through call for resignation hardly achieves anything when the rest of the country does not budge. Some will continue to believe that Trump and Moore are innocent while only Weinstein and Bill Clinton are definitely guilty, even when evidence against all of them are more or less comparable. Will that draw independent-leaning women to shift to Democrats? Miniscule number at most.
Voters have already shown that Hillary Clinton's progressivism does not matter to them. Why continue to act morally virtuous with little to obtain? It's possible to condemn sexual allegations and display an example through political values. Republicans already abandoned Christian values for Trump. It may not be the most ideal choice but it's wiser for Democrats to focus on cultivating candidates that can send out message in a more effective manner than Hillary could.
Democratic values can only be obtained through seats. Numerous candidates of questionable moral values come and go, but a nation's law has profound and longlasting effect, whether for good or bad.
This is a self-defeating argument. Our goal is
better government. The way to get that via the current system is to elect more representatives to government who share our values. While I can potentially support someone who disagrees on
how to make things happen, they do need to share my core values - including no tolerance for sexism, sexual (or other) assault, and the underlying cultural bigotry that leads to such actions and the passive acceptance or encouragement.
My whole life (and really, prior to it) the Democrats have talked a good game, but the people elected in the name of "at least our side wins" have sold out America and it's people again and again, usually to corporations, but sometimes to Republicans too. While I'll compromise a lot in order to stop Trump and the GOP and have a
chance at saving this country for the future, I won't just repeated the failed Dem strategy of the last three decades.
To me, what you're saying sounds like "We should give up what we're fighting for so that we have a better chance to win". My response is that abandoning the reasons we're fighting is just another name for surrender.
