We are trying. I volunteer for campaigns and knock on doors for progressive candidates. And they get attacked by the kind of democrats who take most of their campaign contributions from property developers and car dealerships.
If you are voting for the establishment and attacking anybody who brings up valid criticisms, YOU are not doing anything about it.
"Democrats are not doing enough to encourage people to vote for Democrats." is a warning, not a threat.
People who make and post memes like this seem to think that the people complaining about conservative Democrats and pointing out problems in the party are not voting for Democrats. I think they largely wrong about that. We are voting for all Democrats all the time, but warning you that your messaging sucks and you are not going to get the turnout you need. It is not our fault we were correct.
When I started having issues with the behavior of the church, I started reading into the history of the church, and the history of the Abrahamic religions. I read books written by scholars, archeologists, and anthropologists, not by theologians.
I cannot fathom how anybody learns how Christianity came to be and still believes any of it is true.
They chose the name because they thought it was funny, and they did not realize it was derogatory. They did nothing wrong then, they just did not know.
Once it was brought to their attention, they had two options: they could stick with the name that they now know is derogatory and hurtful (and prevents it from being installed in some places) or they could change it.
This is not an isolated problem in the FOSS community. I was trying to roll out Linux VMs in an organizations, and I got called into a meeting because gigolo popped up a message and the user was confused and upset. Yes, it is a funny pun (it mounts what it is told to), but it ruined Linux for that organization and they went with Windows.
