a) How it's possible, even hypothetically for citizens to simultaneously have both "the right to speak their minds and voice their opinions in public" and "without fear of being shamed or shunned". The two are contradictory.
b) How that superposition is "a fundamental right as citizens of a free country", which Americans once had but are losing.
As or b) - I don't see that there's some kind of grand superposition of opposites at play here like you do, so I'll largely pass. But more broadly: it seems beyond dispute that the the broader climate of public discourse has become more constrained and fear-driven in recent years. Not as bad as it's ever been, or compared to what certain groups have gone through. But compared to 20 or 30 years ago -- the mainstream climate has definitely deteriorated.
