Is this a PETA comment?
The proper comeback for such a comment is something like this.
"This might be true and that is why its imperitive that everyone from the local retailers to the collectors understand how important it is to be educated about what they are collecting, selling and for the hobbists what they are keeping. If this means turning away a customer because the retailer feels they dont have the knowlege needed to provide for that fish, coral, plant or invert than so beit."
Only thru a consentrated education program can we change some of the negitive views that non hobbists have. The arguement made above can be turned around and made for all domesticated pets. Dogs, Cats, Birds, Rodents, etc.
