You absolutely can disagree with me and criticize how I express myself. As I can you. That’s how freedom of speech works in the “marketplace of ideas". It’s a two way street, not a one way street. It works well that way so long as all parties are respectful, protective of their opponents rights to free speech, understand and adhere to acceptable limits, and do not speak in harmful ways (slander, liable, hate, threats, inciting, etc) with malicious or dishonest intent.
In regards to cancel culture, frankly I see it as mostly a red herring or straw man argument by the fringe, the far right, and political conservatives to confuse the public and avoid accountability. That qualifies as malicious and dishonest intent.
I’ve written comments within this thread that explain the hows and whys of that reasoning in legal and Constitutional terms so I won’t reiterate it here.
I’ll sum it up by saying that freedom of speech is meaningless if it isn’t applied to all equitably, freedom of speech is a proscriptive law against the government and does not apply to private companies, freedom of speech is not an absolute, there are exceptions as determined by Supreme Court rulings, the right to say whatever you want does not mean you have no accountability or responsibility for what you say or that others have no right to respond to your speech with their own commentary, civil suits, or their wallets.
Don’t forget, in American law companies also have legal rights of personhood which means they absolutely can fire you if your public conduct as an employee harms their public image. You still have the right to free speech, but you do it privately and/or anonymously or face the consequences if you become a problem.
Other countries with freedom of speech laws will determine their own bounds of it, as it should be. This particular instance involves an American citizen on American soil using an American owned social media platform and an American company so obviously, American jurisprudence and custom regarding free speech will apply because that’s where any suits will be filed and decided if it ever comes to that.
If we were in any other country that recognizes free speech with their citizens and companies, it would be proper and appropriate to follow their laws and customs which may differ drastically from ours.
You don’t have to like it or agree with it, but you do have to follow the laws of the country you are in. We all do.
