Luxembourg Prime Minister Xavier Bettel on Tuesday became the first out head of government to speak about LGBTI-specific issues at a U.N. General Assembly. “Being gay is not a choice, but not accepting it is a choice,” said Bettel at an U.N. LGBTI Core Group event that focused on efforts to end anti-LGBTI hate speech in social and traditional media, according to a tweet from Luxembourg’s Permanent Mission to the U.N. “Homophobia is a choice and we have to fight against it!” U.N. High Commissioner for Human Rights Michelle Bachelet, who is the former president of Chile, also spoke at the event alongside others who include OutRight Action International Executive Director Jessica Stern and Sam Brinton of the Trevor Project. Geena Rocero, a Filipina model and transgender rights activist, is among those who were in attendance. The event took place hours after President Trump delivered his address to the U.N. General Assembly.
