Sounds like the real asshole is the person who instead of trying to understand and critique people with different opinions, simply lambasts them as "assholes".

A great example of the author's inability to engage with opposing views is in the intro:

Afterward, one of the event organizers thanked me for coming, even though, she said, “I disagree with almost everything you said.” Seriously? So it’s okay to evict poor people to make room for new rich people? Is that what the SF Chron talked about today with a story called “psychology studies suggest rising wealth means more jerks in SF?”

Note how the author is more interested in psychology studies about people, than what those people would actually say for themselves.
