You only have to look at opinions about covid policies to realize you won't get a good representation because opinions will be deemed "misinformation" by the powers that are vested in that being the case. Increasingly, criticism of government policy can be conflated with some sort of crime that is absolutely up for interpretation to some government institution so people self censor, companies censor just in casa and the Overton window gets narrower.
LLMs are awesome but they will only represent what they're trained on and what they're trained on only represents what's allowed to be in the mainstream discourse.
