being "a communist but still arrogant and inventing wildly."

I feel personally attacked!

No but seriously, as someone who followed a path which was roughly militant online atheist -> lib debate fetishist -> arrogant communist with nothing but cursory knowledge, I really sympathize with having to work to not fall back into past bad habits. I often find myself furiously typing long comments, then stopping and asking "do I even know this?" or "what am I trying to achieve here?" and then deleting it in shame.
