How is this a Buddhist temple? I certainly see Taoist influence with a healthy dose of Chinese folk religion, but labeling it a Buddhist temple seems quite the stretch.

I'm no expert but I think you're certainly right. Buddhist's temple especially outside of the country is a little funky. Usually, the locals are the one whose determine what's acceptable. If no one complaint, then it would become the norm.

There are Buddahs at all the primary alters. What is the aim of your rhetorical question?

It very good
