Interesting thread. Hopefully it remains honest and respectful.
Agreed with OP on judging ticklishness based on other traits, but similarly, I would like to see an end to the fallacy that once gender, age group, etc, can be regarded as inherently better ticklers. Anybody who gives proper attention to the person they are tickling, and who genuinely enjoys doing it, can potentially be an amazing 'ler.
Also, just got done saying it in another thread, but the belief, rarely explicitly stated, but more often demonstrated in attitude, that f/m is "gay." A man can be submissive, and it doesn't mean he's gay, or a sissy, or that there's anything else unusual about him.
Another myth I'd love to see dispelled is that tickling is always a sexual act. Not that anybody says such, necessarily, but so often in threads about topics related to who somebody wants to tickle or be tickled by (tickling friends, tickling people of the same gender, tickling people you don't necessarily find attractive, etc.) it seems to be very hard for people for whom it's a sexual act to be capable of stepping out from behind that lens and see that for some people, it's not always, or is not at all, sexual. Yes, this is a fetish forum, and yes, there are rules disallowing minors, but this alone does not validate the idea that tickling always has to be about sex.
Lastly the "it's all about me" belief... Many times I have been reading a story or viewing materials that are not foot-centric, and people have come on that thread saying, "Nice pic/story, but why not feet??" There have been threads about m/m material, and people will sometimes view and post on those threads just to say "Ew." I hardly read threads about video content anymore, because there seems to be more criticism of the "bad" videos than talk about the good stuff, and most of it just seems subjective to me. If you are lucky enough that your tastes are among a majority, and generally already catered to on this site, I don't understand why you would take time out of your day to criticize or comment on things you genuinely don't like. If the title of the thread implies it's not for you, it's perfectly okay to not comment.
