transsexual +‎ -ism

transsexualism (uncountable)

1. Transsexuality; the state of being transsexual.
   • 1997, A. Spencer Bergstedt, Transition and Beyond, page 28:

     Transfolk are not covered in any applicable laws like Title VII or the ADA - in fact, transsexualism is explicitly excluded from the ADA. Therefore, you have no causes of action against an employer based on federal law.

   • 2012, Patrick Slattery, Curriculum Development in the Postmodern Era:

     Being a transsexual is not something that can be ignored or suppressed forever. Unlike the fascinations of the cross dresser or the partially altered transgenderist, the absolute compulsion of classical transsexualism is a matter of life and death.

• transsexuality (now more common)
• transsexualness
