That most people in the world don't have a tickle fetish, many don't like being tickled and won't indulge you tickling them - they have had bad experiences with being tickled with it hurting, being bullied with it or being felt up with it used as an excuse. Or they just don't like how it feels. More are probably willing to tickle you, but it's still not a majority or anything close. In other words this is a niche fetish and while you can successfully introduce some people to it, it's gonna be rarer than you would like. This is obvious to most, but we'll some people in the community can't accept this and get irrationally angry if you point this out - they think there experiences / love of tickling are representive of the mainstream vanilla world and they just aren't. You could apply the same statement to many with a foot fetish - best demonstrated to me by one person here who was legitimately shocked when I told him truthfully that the vast majority of men do not stare / perv at my feet or toes, that the vast majority are looking at eyes, smile, breasts, tummy muscles, butt, thighs / legs etc. The number of people I and my friends have caught staring at our feet over the years vs all those other spots is very very low. Of course there is nothing wrong with having a tickling or foot fetish, but it's delusional (and will only frustrate you when you realize it's not true) to think most people share them, they are niche kinks.
