I got no problem with a true gypsy, the sort that travel in small number, a lurcher and a terrier in the horse drawn wagon, yes they thieve and poach a little to feed themselves, they can be a bit of a nuisance.
Travellers are a different issue all together , these are the people that we call travellers, they only travel as far as somewhere they can set up camp on someone else's land and stay there. They use the whole area as a toilet, they cut down large amounts of trees for to their fires, their children run around filthy stinking dirty, they con everybody they come across. When they are finally evicted from land they have taken over, the tax payer has to foot the bill for hundreds of thousands of pounds to clear up the place if they are on public land.
They are the lowest form of human life, and I say human life because most animals couldn't live the way they do.
The above is what happened very close to where I live, they took over a very large picnic area on the moors, it wasn't safe to go anywhere near it for over two years until they were evicted. The council had to remove over 40 caravans and lorries, and the large woodland that adjoined the picnic are is now so sparse, you cant even call it a woodland. Just give me an R.P.G
