Your right to get drunk is not infringed upon unless you endanger the life of others.
It is not my right to get drunk that was in discussion, rather it centered around the loss of respect for personal rights engendered by sobriety check points. FWIW I drink less than a dozen beers a year and am never drunk. But my rights are infringed upon whether I "endanger the life of others" or not. And that is the point.
