Not just LLMs, but a lot of our institutions and information gateways seems to have a strong libleft bias. Universities and colleges are notoriously biased. Search engines are biased. Libraries are biased. Fact finding sites such as snopes are completely liberal. Wikipedia is extremely biased. Majority of books are biased.

The entire news and television ecosystem is biased. Although Trump is "correcting" them towards being unbiased by suing them personally as well as unleashing the power of the federal government. Same goes for social media.
