Listening to all the arguments means you’re going to spend a lot of time wasting your time on garbage. Freedom of Speech protects people’s rights to just make stuff up and get everyone else angry about it.
Within this environment, you can’t really expect anyone to just openly listen to everything. It’s just too much.
Because we have Freedom of Speech, and people like convenience more than challenge. Lets take racism. While it should be fairly apparent that trying to lump any entire group of people all together without acknowledging exceptions is silly, its also very convenient to have a scapegoat you can blame your society’s failings on, instead of looking deeper at your own beliefs and how they might be contributing to your problems.
We can’t do away with the freedoms either, as they, alongside our checks and balances, protect us from totalitarianism. People generally consider education in critical thinking, the humanities and the scientific method to be the solution to all of this, long-term. But, others choose to exercise their own freedoms to attack education itself, which they are free to do.
So, it’s complicated. But in classic democratic fashion, the choice will be up to us in the end.
