No different from the dipwads who insist that using sharpshooters to take out deer overpopulation is "cruel."
They're perfectly happy, however, to let the excess deer run all over the roads, get hit by cars, and die of broken ribs...
Now that I'm more mature,I find firearms more efficient than running down deer and killing them with a narrow bladed shovel. ;)

It's much like the two bulls that see a bunch of cows in the distance and the young bull says,"let's (run) over there and breed one of those cows".
The older bull answers his young partner with,"no,lets just (walk) over and breed 'em all". :o)
