You have your opinion, I have mine. It is no different that not allowing foreigners to vote, or avail themselves of our publically funded service - at least it used to be.
Decades ago, before a legal immigrant to this country could enter it, someone had to warrant that the entrant would not become a public burden. I had to certify this for my wife.
You can word game it all you want, but I suspect if the Founding Fathers were alive today and saw what is going, they would be very much clearer in what they said.
The way I see it is this: People have every right to start a petition calling for the deportation of someone on the basis of exercising their right to free speech, and the government has a responsibility to ignore it for being completely unconstitutional.
Of course, you are free to your opinion [pun intended]. It simply does not hold up very well in the eyes of the law. And someone with the mind of Scalia (sadly, I’m not so smart) would be greatly amused at the suggestion he is playing “word games.”
