Our wildlife is under threat since the Eastern European invasion.
Obviously the likes of the Daily Mail love to exaggerate about Eastern Europeans eating all our swans and carp, but there may be SOME truth in it. Different cultures have different ethics regarding these issues and as a region rich in wildlife people probably do think nothing of poaching the odd waterbird or carp for their dinner in Eastern Europe and maybe some think they can do the same here.
If persons want to start spouting crap based on prejudices, perhaps they could educate themselves a little before posting. The blanket term 'Eastern Europe' covers an area, I presume, from Estonia right down to Bulgaria and Romania, a multitude of cultures and traditions - slurring all with the same brush?
Lithuanians are, by number, I think the second largest group of immigrants now residing in Britain, Poles I think first. In Lithuania, and I'll let Poland speak for itself, there is NO culture of killing swans for sport or food and indeed I would say most hunters are very respectful of laws in place in this regard.
Now let's take a look at wandon killing of wildlife 'for kicks' - whilst not that common in Britain, it certainly more common than in Lithuania. I can recall examples of swans being shot with crossbows on town ponds in Britain, of a baby deer being stamped on for no reason in Dorset, etc, etc. I can remember only one case of a similar event in Lithuania, a person who shot a White Stork - and the person responsible not only was prosecuted and punished, but also had his car confiscated (he had used it in the act) and lost his job (he was a state employee).
Sure, there are bad folks about, and maybe these persons who did this to a swan did come from somewhere in Eastern Europe (or maybe even from somewhere in Western Europe), but using the story to push the usual tosh about habits of Eastern Europe is a reflection on you and your ignorance of the region, not a reflection on Eastern Europe.
