I'm not sure I follow the "illegal" part. The First Amendment limits what the Government can do, not private parties. Private parties can criticize and boycott whoever they want.
Wonder if they’ve ever heard of the concept of reprisal?
...and you have the right to criticize and boycott right back at them.
Understood. But they strive to get the government to illegally criminalize our First Amendment rights. It’s basically a conspiracy of illegality.
