No body is owed a platform.

I grew up in the 80s you had to be a news personality or famous to reach people.

Echo chambers weren't a thing because the chamber was your neighbors and some of them would probably laugh in your face at crazy things or slap you if it's offensive.

When you can join groups where you know it's safe to say whatever, you will, and you'll be emboldened and think that's how everyone thinks she it's dangerous to operate in the world with that level of group think, especially if the group values ignorance and conformity(fascism) over free thought, expression, and diversity.
