To be honest I think it's just exposure to a larger sample size of the population. Reddit, here, and most other social media outlets (barring Facebook, but FB is a weird case) become pretty echo chambery.
Something that I have noticed is that people who stick to Chapo.Chat and Reddit tend to only be exposed to the stuff that gets posted to make fun of liberals, and not the every day liberal take (also conservative) that is still very stupid.
I think it also tends to make us forget that liberals outnumber us by a lot. There are far more people in the US who support the Status Quo than those who want to overthrow it.
No such thing as too cold too shoot.
Think Murphy's law, but add in the cold.
