The ASPCA does not promote BSL:
"It is, therefore, the ASPCA’s position to oppose any state or local law to regulate or ban dogs based on breed. The ASPCA recognizes that dangerous dogs pose a community problem requiring serious attention. However, in light of the absence of scientific data indicating the efficacy of breed-specific laws, and the unfair and inhumane targeting of responsible pet guardians and their dogs that inevitably results when these laws are enacted, the ASPCA instead favors effective enforcement of a combination of breed-neutral laws that hold reckless dog guardians accountable for their dogs’ aggressive behavior." Per their website.
