Providing the reasoning behind conclusions can also help- “I believe that unlimited migration is harmful to those poorest of those already here and that the rule of law is incredibly important, so I’m opposed to extending a path to citizenship” or “all human beings deserve the same dignity and from a practical standpoint an undocumented immigrant that has been working, paying taxes, and staying out of trouble is more worthy of citizenship than many who gained it simply at birth, so I support a pathway to citizenship.”
Both statements may still be problematic depending on the circumstances (where depending on the circumstances, the best option may be to say nothing) but they are far better than saying “illegal immigrations wrong” or “giving people a pathway to citizenship is the right thing to do.”
