Given how many socialist movements have been declared terrorist groups, yes.
Once again, you think "socialism" is liberal fluff about giving money to poor blacks for no reason, instead of forcing the United States to invest in its own people and not treat them as disposable, rootless consumer trash. Anyone who is pro-illegal immigration is not a socialist. Anyone who is brainwashed into thinking a corporation is their friend because they drape themselves in a rainbow flag is not a socialist. Anyone who thinks that working-class Americans are "deplorables" isn't a socialist.
