Do not let the bad actions of the extreme corrode your civil rights - the right to free speech is both a fundamental human right, and that enshrined in the US Constitution with the first amendment. Banning trucks because terrorists have routinely driven over civilians to wreak havoc, is no way to deal with the matter
I fully support the US government, and it's upholding of the first amendment on this matter: "It cited freedom of expression and freedom of the press as reasons it would not be joining the agreement, and said promoting credible, alternative narratives was the best way to defeat terrorist messaging."
