There are several posters who seem to be strongly opposed to dropping the dog at a shelter. Not all of them are making extreme posts, but all agree that the OP has a responsibility to keep the dog.

In this thread specifically?

I wonder are there really that many crazy dog people on dcum (the kind that post such things as "I would rather you drop your baby off at a shelter than your (aggressive) dog"?

Is it several different people posting, or just one or two people posting repeatedly?
