Calling Israel an Apartheid State seems to be dangerous to people's liberty. What happened to freedom of speech? In the US, it is a federal crime to boycott Apartheid Israel.
To elaborate on what seems like a wild claim - https://en.wikipedia.org/wiki/Anti-BDS_laws:
Most anti-BDS laws have taken one of two forms: contract-focused laws requiring government contractors to promise that they are not boycotting Israel; and investment-focused laws, mandating public investment funds to avoid entities boycotting Israel. [..]
The Anti-Boycott Act of 2018 [..] does not target boycotts against Israel specifically, but makes it illegal to “comply with, further, or support any boycott fostered or imposed by any foreign country, against a country which is friendly to the United States” [..] and as the Office of Antiboycott Compliance notes “The Arab League boycott of Israel is the principal unsanctioned foreign boycott that U.S. persons must be concerned with today.”
