The boundaries have always depended on who you are. Most of us aren't billionaires with the office of the president of one of the wealthiest nations on Earth, the services of the strongest military on the planet, and millions of admirers to shield us.
This extremely perverse situation tells us a good bit about a lot of our fellow citizens but nothing about what the rest of us can get away with nor the constraints placed upon us.
If I said something that was misconstrued sufficiently enough for thousands of people to hear about it and hate me even wrongly I wouldn't be giving up my position at MIT I would probably end up homeless until lack of Asthma medication caused me to suffocate.
Part of that not having billions of dollars to fall back on thing.
