The domain itself suggests overwhelming political bias.
Every forum has an overwhelming bias. You just choose what bias you wish to consume.
What is that based on? It's not my experience, and it seems like binary reasoning: Either no bias or all bias. Everyone lies, for example, but some are far more honest than others. Every developer writes bugs, but it would be ridiculous to say everyone's code is 'overhelmingly' buggy.
