If “immigrants” have rights, who gave them the rights and who guarantees them?
We are talking here anyway about illegal aliens, not immigrants. Illegal aliens have no rights at all except for whatever rights, if any, they might have in their own country. And they have those rights only in their own country.
As far as illegal aliens from Mexico, or anywhere else, they are uninvited, unwanted and should immediately go home. If they want to come to this country go through the legal process.
