I am actually going to the IDAHO celebrations in Havana this year. I met Mariela last year and she was kind enough to invite me to speak. It promises to be a great event, kicking off on May 7th. The big march will be along the Malecón on Friday May 17th.
We often forget that it was not until 1973 that the APA removed homosexuality as a "disorder" from the DSM; and it was not until May 17th 1990 that the WHO removed "us" from its list of diseases, which is why IDAHO is celebrated on that day.
Although Havana (I mean the city, and the government) is becoming increasingly tolerant of LGBT rights (the first "government approved" gay bar opened last year...inaptly called "Las Vegas"), anti-homophobia continues to be a major problem out in the "provinces". When Mariela told me that you can't expect everything to change in "just 50 years of revolution", I told her that they had actually only been working on LGBT rights for 6 years, since she started CENESEX (the, again inaptly, named "National Center for Sexual Education", which is basically the Cuban government's LGBT "ministry").
But they have done a truly amazing job in the fight against HIV.
Again, I would ask anyone who can to try to make it to Havana for what promises to be an amazing couple of weeks.
