Who wears a business suit to clean fish? PETA=people who never had a dad and hate anyone who has one.
I know, but a couple possible reasons for what he was wearing:
1. Due to PETA members' general stupidity and ignorance, they were unaware that a suit is not what one would normally wear while cleaning fish.
2. They were trying to portray him as what ultra- liberal morons consider to be evil incarnate: A white businessman!
The comic/ tract itself is completely repulsive, even for the vermin at PETA who every day seem to find a new low to stoop to. In it, fathers who go fishing are compared to child abductors. It ends by saying (No joke) "You have to make your daddy throw out all his fishing gear and promise to never go fishing again! If he won't do that, you'd better keep your pet dogs and cats away from him, you never know when he might want to kill them next!"
