Let’s get a dictionary….
I have a friend that is a wordsmith, of sorts, and always looks at the roots of words.
Look up the roots of all, the aforementioned word… And, throw in Criminal and Illegal. Or add legal and non-criminal … but for this argument lets stick with Immigration, Criminal and Illegal.
Now, why would a person who says they want to fit the first words definition? Do so by also being the definition of the last two words?
Argue that out.
