As to the bolded, what in the world are you talking about? This doesn't happen in the US. Antifa isn't even a presence here. It's barely even a presence anywhere.
As to your second sentence, all I asked was a question. What would you propose, since you're against federal legislation, and the states cannot do this at their borders?
And on edit, I'm going to add: We're not going to deal with fake news here. Either substantiate your first sentence with real, mainstream media (Fox and WSJ are ok, Alex Jones is not) or your comment and my reply will be deleted. I want to see reliable reports that "Antifa" is conducting state border searches using the buzzwords "bigot, racist, fascist, and homophobe." You dig?
