The May 17 Day is going by many different names and acronyms, and that’s OK.
We, the Committee who create the Day back in 2004 and are managing its global visibility we use
IDAHOTB and IDAHOBIT
We have seen lately that several groups translate the “I” with “intersexism”. We are not sure what they mean (we found no occurrence of the term in any dictionary nor website of any Intersex people), and it is absolutely undisputable that the Day also includes Intersex-phobia, which is the rejection of Intersex people.
So we ask people to please refrain using the term “intersexism” and prefer intersexphobia
