menen, define 'sane adults'. grown people who don't like pony?
last time i checked watching a show about marshmallow colored equines didn't make you a nutjob
most 'sane adults', in my experience, are OK with strange hobbies as long as you don't traipse around showing everyone how awesome your custom-knit Fluttershy plushy is and start making out with it in public or something
