No one from my immediate surroundings would even know the term.
Pretty much the same here. Nor do they know about my penchant for hentai. Most people in my vicinity you could ask what anime is and they'd think it's a thai noodle dish.
I want to say I'd laugh to their stupid faces for being idiots, as I'm not really much interested in anime/"otaku" "subculture"/japan/... beyond hentai; but to be frank I really couldn't give tuppence either way. I guess this is the one and only point where my arrogance and olympian disdain for other people's opinions comes in handy.
