The United States has the strongest laws for freedom of speech. You can't get arrested and face years of criminal legal trials, ending in an £800 fine for making a joke with your dog in America. Police won't show up at your house for Facebook posts like they do in Aussiestan. American courts probably won't take your infant away from you and force a medical procedure on it like in Kiwistan just because you wanted to use your own blood donors for the operation.
It's been degrading in the US too. Xitter is not at all a free speech platform and that technocrat says whatever he has to for popularity until he can chip your brain. Cutting a few million in wasteful government spending doesn't make up for how he loves China and deeply desires their level of autocracy.
America's laws have somehow held in-spite of presidents that seek to crush it (yes, both of them, both sides. They're the same. Stop believing the headlines and read the damn articles). Although defamation law has been weaponized to neuter some forms of speech and reporting.
There is an internal push by the CIA in America to further destabilize it and cause radical elements in the fake-left and fake-right to call for more authoritarianism. It's not a great nation, but sadly it is the last bastion of true liberty .. and it's eroding every day from every side.
In 20 years there might not be anywhere to flee to. Fight for your country. They can't put every British person in prison if everyone decided to tell the truth.
