Can I bring in to this, all the immigrants legal or not ,who move to various countries and do not want to conform with that countries rules, and laws, and actually hate and despise the residents of that country to the extent of terrorism.
This is happening here in the UK, like it or not  "FACT"
I totally agree with Jack,that as humans, we should all be free to move to wherever we want, but there does need to be correct control,s of who is allowed in and who is not.
