Well said -the shallowness in the Remain argument is that they try to stigmatise the Leave position as being AGAINST immigration when in fact we just want control. That is most likely that wanting to be in control is entirely sensible and cannot be lazily labelled.
Britain has less immigration and migration than other countries in Europe. We need extra workers in this country when there is an aging population soon to be on pensions with less people to pay for it.
Any rise in population has been exacerbated with a government cutting resources to local areas putting a strain on services at a time when these extra workers have settled.
No countries border controls are perfect but what the outers want is to bulldoze the house because they see a problem with the door.
