As Ashley said, the control on immigration doesn't bother me (like you said, it's probably not going to change much).
What I'm scared about is that racists in this country now seem to believe that 52% of the country agree with them, and all the shame of being a racist in public appears to have disappeared.
Whatever happens politically in the future, I'm not sure what we can do to solve that problem. That ship has sailed, letting the cat out of the bag and allowing the horse to bolt as it does so.
