Even ignoring the erroneous attributions, I wan't the right to voice a controversial (or even wrong) opinion. Afterall, how else would I engage and learn that I am wrong.

It seems that the expectation is increasingly that the only evidence people should need to overturn their personal opinions is the fact that they are not in the majority.

Similarly, it seems that very little leeway is given to those who changed their minds, even before their controversial opinions came to light.
