ROFL!  Yo, Neutron, what about the fact that tickling, in and of itself, isn't a fetish for everyone.  See previous discourse on that, but simply put, tickling ain't a fetish.  
Just 'cause folks label it as such don't mean a thing.  Some think that such behavior is crazy, bad, wrong, weird, etc.  I'm hopin' that you don't give 'em any credit for such a daft notion.  Personally, I slide "fetish" right in there with the rest.  There's a definition for fetish, and this interest don't fit it.  It DOES fit deviancy, kink, and even sport ('specially for those 2+ hour 'lees), but it's not a fetish.  It's a paraphilia.  Havin' an interest in feet is a fetish.  Shoes, too.  Non-animate objectifications, as targets, are able to be fetishes.  This ain't, really, for many here.
Mind ya, there's naught wrong wit' a fetish, either, but if we're t'discuss the word, it's the wrong word for me, and for a bunch of others here.  Inaccurate.  Misfocused.  Wrong.
Given that last Saturday's gathering had two multi-hour 'lees, that's more a sport, son. 😉  Endurance level trainin', even.
