As of August 2017, 73 countries as well as five sub-national jurisdictions have laws criminalizing homosexuality, with most of these being African and Islamic countries. In 2006 that number was 92. As of May 2016, 16 countries have an unequal age of consent law.
In 2011, the United Nations Human Rights Council passed its first resolution recognizing LGBT rights, which was followed up with a report from the UN Human Rights Commission documenting violations of the rights of LGBT people, including hate crime, criminalization of homosexuality, and discrimination. Following up on the report, the UN Human Rights Commission urged all countries which had not yet done so to enact laws protecting basic LGBT rights.
According to Aristotle, although most "belligerent nations" were strongly influenced by their women, the Celts were unusual because their men openly preferred male lovers (Politics II 1269b). H. D. Rankin in Celts and the Classical World notes that "Athenaeus echoes this comment (603a) and so does Ammianus (30.9). It seems to be the general opinion of antiquity." In book XIII of his Deipnosophists, the Roman Greek rhetorician and grammarian Athenaeus, repeating assertions made by Diodorus Siculus in the 1st century BC (Bibliotheca historica 5:32), wrote that Celtic women were beautiful but that the men preferred to sleep together. Diodorus went further, stating that "the young men will offer themselves to strangers and are insulted if the offer is refused". Rankin argues that the ultimate source of these assertions is likely to be Poseidonius and speculates that these authors may be recording "some kind of bonding ritual ... which requires abstinence from women at certain times".
Throughout Hindu and Vedic texts there are many descriptions of saints, demigods, and even the Supreme Lord transcending gender norms and manifesting multiple combinations of sex and gender. There are several instances in ancient Indian epic poetry of same sex depictions and unions by gods and goddesses. There are several stories depicting love between those of the same sex, especially among kings and queens. Kamasutra, the ancient Indian treatise on love talks about feelings for same sexes. Transsexuals are also venerated e.g. Lord Vishnu as Mohini and Lord Shiva as Ardhanarishwara (which means half woman).
