Trump's crazy designation of Antifa as terrorist organization - 2020-06-01
(CNN) President Donald Trump's announcement that his administration will designate Antifa as a terrorist organization is surely unconstitutional because it would effectively criminalize joining an American domestic ideological group.
Thanks to the First Amendment, the US government has historically avoided designating domestic groups on both the left and right as terrorist. Belonging to such groups is consistent with the legitimate exercise of your First Amendment right to freedom of speech and belief — whether you are a white supremacist or an environmental activist.
Of course, should an American citizen commit a crime in service of her extremist beliefs she can be prosecuted for that crime, but she can't be prosecuted for merely belonging to the group, no matter how objectionable its views might be.
