> Hearing something you might disagree with is part of life and very important to critical thinking.
I believe this is 100% true. Unfortunately, the vast majority of people do not have the skills to handle this. Look at the anger that appears on this site when certain topics are brought up.
So people have a hard time dealing with ideas they disagree with, but I doubt that forced interaction with those ideas will improve the situation.
We can see empirically that the most common reaction is to double down on your own ideas, get defensive, and generally react in a very self-centered and egotistical manner.
That's the current situation. Would banning political ads make this problem worse? I think I can see the logic here - people will only seek out what they agree with.
But it's not like political ads are the only way that they might be forced to see something they disagree with. The only way to do that these days would be to be completely off grid somewhere and never to see anyone else.
It's also the case that political ads probably provide the worse kind of perspective of views you disagree with.
The solution to the problem is to find a way to get people to break out of their ego-based thinking. A lot of magical things can happen when people are honestly committed to finding the truth, instead of protecting what they think the truth is.
