@mcc@mastodon.social I lost the link, apologies, but was reading an interesting argument the other day that transphobes focus on AFAB adolescents and AMAB adults so that either way, they can hand-wring about the "purity" of young girls — either in the Irreversible Damage sense of stigmatizing transition for AFAB teens, or in the "men in locker rooms" sense targeted at adults.
(Apologies for as much essentialism as is embedded in A*AB, trying only to describe the essentialism used by transphobes.)
