True but it's a minor point. Even if every single lefty held the line it wouldn't have made a difference. The people who didn't vote were mostly disengaged normal people and the blame for that is squarely on the Democrats for sucking absolute shit on purpose because of big money in politics.
Have some perspective, pick better fights with worse people. I personally find it extremely unmoving when the left chastises people over politics so good job emulating one of their worst and least politically effective qualities.
Instead, I humbly suggest you try to inspire a shred of hope among the cynical and apathetic - but deep down actually very cool people of the Earth🌠
