I don't have a problem with them. I think they're usually wrong and often haven't really put critical thought into the consequences of having big bureaucratic systems run everything, but getting bullied online is a good way for me to have to challenge my beliefs. People are mean on the internet and even meaner in real life. It's good to develop tolerance to bad faith criticism when all that's at stake is some words on a screen.

The left does make sense as a cohesive group because of our shared values. We differ in our methods and that's what we spend most of our time fighting over. I bet we both agree with that jerk whose comment you linked that pedophilia and drunk driving are bad, we just don't agree on the best way to deal with it. The way we stay cohesive is by reminding ourselves that, at the end of the day, we all want to make a better world.
