Making "nothing gringo" really count
All they have to do is tell people to make the boycott permanent -- of illegitimate commerce. After all, everyone should already have been boycotting, for instance, pornography stores and other stores that sell pornography; video stores and their pornography; devil-made products such as condoms and contraceptives; and abortion centers, especially Planned Parenthood.
Now, in case you are wondering: No, I do not think there is any chance of the Cardinal and his bishops and pastors making a big public call to do this. But they ought to!
Also, the Cardinal and his bishops and priests could tell everyone to find out which politicians in each party are pro-abortion, pro-homosexual and anti-family, and to shun them forever.
"Nothing gringo" should come to mean that people permanently refuse to adopt anything and everything in the USA that is part of sin, decadence and the Culture of Death.
For instance, specifically for people who come here from Mexico, "nothing gringo" should come to amount to the same thing as "Mexico siempre fiel" -- "Mexico ever faithful." Amen!
