As long as Faithful Catholics don't try and legislate their morality? 

Do you have a problem with Faithful Catholics trying to legislature Catholic social teaching? Why do Catholics get to legislate their values on social justice, but not their moral values?

If you are going to be consistent, then we can't impose Catholic social teaching any more than we can impose Catholic moral teaching.  That means we need to stop supporting immigrants rights, refugee rights, we need to stop campaigning against the border wall, etc.  After all, we mustn't ever impose our values on people through the law.
