Right off the bat, what's silly about this premise is that it refers to the The Bechdel Test as something that "Feminists came up with" assuming some kind of uniform hive mind, instead of something that one person named Alison Bechdel came up with.
Some googling reveals that Alsion Bechdel is a cartoonist. Apparently the "Bechdel Test" was originally mentioned in 1985 in a comic strip called "Dykes to Watch Out For". It's something that an unnamed non-recurring fictional character discusses as influencing her movie choices, though i can't imagine how someone could know this about a movie one hasn't seen, especially before the internet.

Essentially, I think it's ridiculous to assert that "feminists shouldn't like" anything for any reason, but as a universal gauge, the Bechdel test is particularly iffy. It's useful for illustrating how the media fails to reflect the reality of the world we live in, but it's only one dimension out of several. The wikipedia article on the Bechdel test has a section on "limitations".

A work can pass the test and still contain sexist content, and a work with prominent female characters can fail the test. A work may fail the test for reasons unrelated to gender bias, such as because its setting works against the inclusion of women (e.g., Umberto Eco's The Name of the Rose, set in a medieval monastery).
>>In an attempt at a quantitative analysis of works as to whether or not they pass the test, at least one researcher, Faith Lawrence, noted that the results depend on how rigorously the t
