The owners of little lap dogs (not that there is anything wrong with lap dogs) seem to hate "pitbulls" the most.
The whole show dogs thing is weird to me - many of the AKC dog breeds seem to have all function breed out of them - at least the lap dogs don't pretend to be anything other then small pets that look cute.
I have two Labs and I hate pit bulls with a passion. They are nothing but a dog mauling waiting to happen.
I am neutral on lap dogs, but would never have one.
As far as laws against pit bulls goes, there are laws agains keeping lions, tigers and all manner of dangerous animals in your house and no one complains. Pit bulls are just another type of dangerous animal.
I have noted that both the socio-economic status and the intelligence of the average pit bull owners is well below the norm for owners of more gentle breeds. Seems like the dumber the person, the more vicious the dog they like.

Worse. They favor looks over function which results in breeding problem traits associated with looks they want - breathing problems, genetic diseases, poor health, etc.
