Yes. For example, very few people in SV can openly say they are going to vote for Trump.
> the larger the audience and concurrency of engagement, the less people censor the them selves
Yes, people don't censor themselves when they are in majority. For example, those who live in SV, and support gay marriage and BLM, they can throw insults without repercussions.
The fun fact about the word "bigotry" is that people who use "bigotry" as insults are very often bigots themselves.
Not treating people with respect, regardless of their views, is also bigotry.
