i think you are most stupid. who said all 7 billion immigrants have right to be here. the federal judge's jurisdiction doesnt go beyond US laws and territory. travel ban to the nation on the basis of religion is against the constitution. if you go through US constitution you can find that even the president cant ban anyone entering US on the basis of sex religion and ....so on. get some common sense bro.
and to be a federal judge you gotta master science of LAWS. practice it for years. and now you whose name itsself is controversial teaches how to give a verdict..lol
