There is literally no other viable option at this point.
This is what happens when 30 years is spent calling anyone concerned about immigration 'racist' - the word is now meaningless.
Erm, ... ''legally'' .. you mean having to face a bunch of unelected judges from blocking a deportation mandate given to the government by the people ?
