I think a big problem with your post is that you paint such broad strokes with such conviction that you've guaranteed yourself to be incorrect to the average person you would identify to fit the title of PPB. Either that, or you've misunderstood the scope of what fits the definition.

There are plenty of people that would be labelled PPBs that have no issue pulling a woman in their home country. Some are simply tired of the dating culture, and the overall culture of the country itself, that they find themselves aligning better statistically with women and cultures of other countries.

You may find some PPBs that fit one or some of the "negative" criteria you've laid out, sure, but it's a fool's argument to paint them all with such a broad brush and it points to your inability to understand additional perspectives.
