First of all, welcome to the Forum.
I don’t think what you say sounds over the top at all. I do feel for you. It can be very upsetting seeing your ‘old friends’ arriving with bizarre marks on them. As you will realise from reading other items on the forum I am not in favour of marking hedgehogs unless it is part of a properly organised scientific study for the benefit of hedgehogs, which I believe would normally require a licence. It is particularly sad, when it is possible to identify hedgehogs from their natural markings, given a small amount of effort. I agree that it would be good if hedgehogs had better protection.
