I assumed that you did not actually believe that all criminals in America had assaulted someone, but if you did not believe it then arguing for the punishment of people who did not commit violent acts (by making it more difficult for them to get jobs when released) seems far worse than if you just did believe a ridiculous thing.
And really by using in your argument an emotional hypothetical about the assaulted to argue for denying something to people who have not committed assault it becomes difficult to know exactly how to take it.
The argument is hard to take seriously if you don't really believe it is true for all criminals, and it is difficult to believe you think it is true for all criminals.
