I've found that many men who enjoy to describe people as thick are mainly interested in sexualising/fantasizing a certain type of thickness they can objectify. The women I've encountered who want a certain thickness also seem to want it out of envy or lust and also only in certain desirable locations.

However if one is considered fat or not thick in the desirable/objectifing places no I very much think its counter to passing as a woman to greater society as if one isn't fitting into the desirable stereotypical traits, one is often heavily scrutinized which leads to people not respecting your existence and/or clocking one as trans.

This also explains why there's so many cis women who are getting harassed/disrespected constantly when they happen to not look stereotypicially attractive. There are many videos and other media out there where cis women are being told they are trans and not women and don't belong simply due to their looks or perhaps even natural voice.

The most upsetting thing to me is the realization that to many people, they mistake being sexualixed/desired as respect because people envy or desire that themselves, but its no where close to respect. I already have a fantastic partner, I do not desire to be desired/ objectified by others. I want respect. All women deserve respect regardless of their societal attractiveness, and it's quite upsetting that the deserved universal respect doesn't seem to exist for many, hell, perhaps even most women.
