Well doing a helpful personal calification of fetishes:
-No controversy: Basically it's incredibly weird to see anyone commenting against those, in this group we would have titjob, blowjob, vaginal... it is the "safe space".
-A bit of controversy: There can be people that have a hard pass on them but they tend to be generally acceptable, in this group I would put feet, cloth related stuff such as pantyhose, impregnation/pregnancy, anal and light versions of femdom and maledom (I mean it when I say light).
-Controversy starts: here I would put fetishes that give a weird feeling but it doesn't go to the disgusting side for most people, just weird, we would have stuff like armpit sex for example, actions that start to be felt generally as weird.
-Advanced controversy: I would put here all fetishes that tend to generate controversy just by the mere existance, NTR, hard maledom and femdom, voyeurism, furry (albeit this one depends on levels to be fair, light furry such as catgirls or similar stuff tends to be quite accepted), on this group tolerance tend to be low by some groups if not non existant.
-Total controversy: Basically anything that is totally disgusting if you don't have the fetish, horror, scat, piss, gore, amputation and similar stuff are in this group. This is the group of "you have it or you hate it" for the most part at least.
Some people may classify it a bit different but I would say that for the most part this is kind of the tolerance lines.
Leaving that aside and going personally I tend to be very tolerant, only those that are on my total controversy classification are those that I evade, on the part of fetishes the only truly fetish that I seem to have is "domination win", in the sense of how poor to riches tend to go but on the sex aspect, you tend to start on an inferior situation (slave, in debt, risks everywhere...) overcome them and end up being the dominant partner, an easy example to visualize would be a slave maker type of game playing as a slave and managing to change the roles with the slaver thanks to your efforts.
It isn't as simple to explain as having a boob fetish but that's about it lol.
