@Daddy_AnLi brought up the problem of submission fetishists VS subs, and that talking about it could be pretty frustrating because the former got offended to be described that way. I am taking a stab to explain the why. Is thread.

A "submission fetishist" is a term coined to refer to the people who have a very limited number of kinks that are the be all and end all of what they can and will do. They are the people who want to be "forced" or ordered to do what they already want to do and ONLY that.

Contextually there is nothing wrong with having kinks, the break down is the self description of being "a submissive" causing the dominant frustration when they discover that submitting to the more variable commands of the dominant is no beuno. The dominant feels denied.

But SFets aren't likely to be happy to have their kinks framed that way. In the first place they are aware there is a hierarchy and that it is phrased as "just" or imperfect or incomplete.
We put "true" subs as more desirable.

And one of the crux points of the fantasy is the desire to feel submissive. Granted most of the time these people are as useful as teats on a bull, but a huge component of a lot of sub guys is imagining if only they could be perfect in vulnerability. Busting that fantasy is valid

But 0 people who are Sfets are going to take well to it as framing because it completely tears down all sorts of cozy, basically romantic fantasies about themselves.

Bonus: Ironically we flip it the other way and tell pros they are "not true dominants" because they can cater/tailor and are not just arbitrarily doing whatever whim pops into their head. This is obviously also nonesense if you spend 10 minutes around pros.
