We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Aquinas lived in a society that respected learning. Thanks to Rousseau, Derrida, et al, ignorance now lays equal claim to respect as knowledge and reason. The damage done by postmodernism makes the kind of respectful public arguments for which the bishop calls utterly impossible.
Yes, it would make sense to engage in active, thoughtful debate, However, those repressing free speech are insecure with their arguments and beliefs. They do not think they will stand up in the arena of free speech, regardless, they believe them because they want to believe them. Often these people live as if their ideology is true and they do not want people around them reminding them that they are not.
My 7th & 8th grade teacher taught his classes to debate. We never knew what side we had to take until 10 minutes before when we were allowed to confer with our team. This insured that we had to be well versed in both sides of the argument. I've always appreciated those lessons as they have served me well both personally and in my career. Sadly, these snowflakes are ill prepared to consider the various sides of any issue and use yelling and thuggery to drown out any potential learning experience.
