A very over-the-top political commentator complains that, despite the First Amendment's protection of freedom of speech, he still suffers social stigma and exclusion for his opinions and that this is unconstitutional.
Sorry, dude. The Constitution, at least the original one with the Bill of Rights, limits the State, not the citizens. If you say unpopular things and people exclude you, that's their right. The government is not supposed to take action against you, but everyone else is free to react as they will.
It ain't nice, but it's not unConstitutional.
PS I take the same viewpoint on the issue of "no religious test" for public office. That limits the State and not the people.
