How is it best to clarify "The small number of comments against owning pets don't even need to be included"?

A. Not enough people can give legitimate reasons to not own pets.
B. The majority of people favor pet ownership, so the writer does not mention arguments against the majority.

I can't decide, but I think it is B?

First, the paragraph has a grammatical error. The subject is "number," so the verb should be "doesn't."

I lean toward A.
