Hunters are 'serial killers'.

[Hepcat]

I would imagine that any attempt at a debate would be met with a wave of insults, rantings and usual anarchist rubbish. You may as well ask the animals for their opinions because you would get a much more reasoned statement.

For example:
"So Mr duck, what is your opinion of hunting and the effects on the ecology. There are those who claim that murdering animals should be a crime. What do you say to that?"

There, that is much more sensible than anything the Greens have to say.
