Per the 14th amendment, deportation/revocation of rights to be here only pertains to non-citizens, and denaturalized citizens who've gone through due process
A person born in the US (with birthright citizenship, which was affirmed in 1868) is not subject to removal unless they officially renounce their citizenship...and even then, there has to be another country willing to take them in...you can't just load people up on a bus and drop them off in Vancouver or Windsor, Ontario...that's not how it works.
And in a legal sense, "deporting" a person born in the US is impossible. Since "deportation", in the legal definition of the process, is "the removal of a foreign national"
Natural born citizens blocking traffic on a bridge waving Palestinian flags may be idiots, but they're not foreign nationals, therefore, can not be deported. They can face other consequences for the litany of statute violations they're committing with their actions...but removal from the country isn't one of them.
