The something practical is to join the various groups of citizens arrayed along the border to help in the effort to stop illegals. This is as tough as it gets, unless we want to start shooting them on sight.
As far as one's political demise: You have to choose sides in this. You can't deal with a problem that has no political solution, with politics. This situation is a great deal more important to the country than the next several elections. The law is clear, and Americans have the right to protect their property.(And I don't mean only that property along the border. Helping those at the border helps me in the city.)
The point is for you to screw up the courage to go and stand an armed watch on the border with other right thinking and patriotic Americans. To hell with the media, and to hell with politicians who won't protect us.
I can't do that. I have a special vow to God that prevents me shooting civilians. And I can't recommend it for the same reason.
