> Should we just abolish the idea of a free market of ideas?

Yes, please! This has never existed in the past, and continues to not exist in the present, and seems to me logically impossible to ever exist in the future.

Just like many would not consider Fox News to be "fair and balanced", but instead consider this slogan to be a dishonest attempt to obscure Fox News' bias, the sooner we give up on the "free market of ideas"-style sloganeering the sooner we can approach problems like those discussed here with any sort of honesty.
