Trying to be fair-minded, I must add that there is in UK a massive over-population of all kinds of deer. (roe, fallow, muntjac and red for example) and every year there should apparently be a cull. If not, the numbers get ridiculous and there's damage to forests (tree bark and saplings get nibbled and eaten) and the deer themselves are left hungry. Also, here in Norfolk the deer have ticks which give rise to Lyme's disease if they bite a human (I was bitten once, a typical 'bullseye' mark, but had emergency antibiotics which swiftly dealt with it.)
When I lived in Glasgow, there was a restaurant there (near Byres Road I think) called The Ubiquitous Chip. They served a delicious venison casserole, which I indulged in many times. Very strong-flavoured and a bit tough but I adored it. I expect this was the meat of the red deer.
