I think whenever we see someone complaining about the Federation or otherwise not wanting to be in it, wanting to leave it it seems to be just general xenophobia/species supremacism but could there be other reasons that are not at least directly based on antagonism against others?
There can be argument that being part of huge organization makes it, and all parts of it, too much of a rival to/target for other powers but the Federation does seem pretty genuinely non aggressive, only defensive, and the other powers just generally aggressive, hard to see how they wouldn't just as much or more go after smaller groups, societies or just individual planets.
And the other major reason for preferring independence is just to have/allow more autonomy and sovereignty but the Federation already seems to let its worlds have a lot of that, very few actual requirements or limitations.
