In my opinion you can't value independent thoughts and diversity, without being inclusive of different opinions and setting the same standard of discourse regardless of which viewpoint you are furthering. Because if not who choose what the correct viewpoints are? And are you sure your viewpoints will always stay popular?
Although what we value is very different I am not so sure that we are all that different at this point from China, except for this being enforced by a state sanctioned monopoly on violence in China while its now too often mob-rule violence in the US that I am not confident would be upheld in the courts.
Fighting for what you perceive as justice in a democracy is rarely furthered well by authoritarian means, and should be done through the democratic process and you should respect that the state has a monopoly on violence. Freedom is a fragile thing, and democracy is not the default state of society.
