Did a horse rape him? No?
Nobody here understands how bias works.
"Bias is an inclination to present or hold a partial perspective at the expense of (possibly equally valid) alternatives. Anything biased generally is one-sided, and therefore lacks a neutral point of view. Bias can come in many forms."
"A cognitive bias is the human tendency to make systematic decisions in certain circumstances based on cognitive factors rather than evidence. Bias arises from various processes that are sometimes difficult to distinguish. These processes include information-processing shortcuts, motivational factors, and social influence."
Bias doesn't have to be based on experiences with something you're biased against.
Although it could be said that MLP being posted on the Blockland Forums has brought his opinion to be biased towards the discussion/ mentioning of it outside the topic.
But okay.
