If you are actively trying to use social and economic pressure to prevent someone from being heard then you are trying to limit their freedom to speak. I agree about the snowflake problem of people wilting when they hear something they don't like. I also agree that NBC has the right to interview anyone they choose and the boycotters used threats of economic sanctions to prevent them from doing that. So I guess I should have included freedom of the press being attacked as well.
My point is that these days there is a bigger threat of censorship of speech and the media from these extremist activist then there is from the government and it is just as dangerous, if not more so since it is harder to regulate. A lot of the back lash that gave us Trump in the White House is people angry because they feel their point of view is being ignored and they are attacked for having it despite that fact that in most cases they are mainstream views. Extreme partisanship has become a growing threat in this country and the idea that we can just shut up anyone we don't like is only making it worse.
