That’s because the left are the people who actually care about logic and morality. Things have to be consistent, and competing beliefs are almost always about things that you have 90%+ agreement over but are stuck arguing over a semi-colon in the wrong place. What sucks is when you get people on the left who are clearly out-of-bounds and inconsistent with progressive beliefs. There’s enough people on the left that know (and are fully 100% correct) in the idea that women and people of color and trans-people need representation, and there’s enough people on the left that don’t want that at all (especially in America) and are willing to fight to keep it that way even if it means dragging that fight into the open for everyone to see.
The right doesn’t care about anything, not really. They will disregard the first part of a paragraph by the time they get to the end of the same paragraph. They will lie, cheat, steal, and murder to get anything they want because, unfortunately, they fully understand that humanity is fucking ignorant and they use that to their advantage.
