It is not illegal to identify as gay in the deeply conservative Muslim nation, but same-sex activity is already punishable by up to five years in prison.
Religious leaders and civil society figures addressed hundreds of jubilant protesters, who had gathered in a central square for the rally organized by And Samm Jikko Yi, a civil society collective that promotes “correct values”.
Ousmane Kouta, a representative of a student religious group, told the crowd that Senegal is a country of faith and values.
“It is homophobic and will remain so forever,” he said, to cheers and chanted slogans.
Aminata Diallo, a member of an association for young Muslims, told AFP that she attended the rally to protest homosexuality and demand its criminalization.
Other protesters were more extreme.
“We will kill them, or we will burn them alive. We’ll never accept homosexuality,” said 56-year-old municipal official Demba Dioup.
Senegal’s government has repeatedly ruled out legalizing homosexuality.
Consensual same-sex relations are legal in 21 of 54 African countries, according to a 2019 report by the International Lesbian, Gay, Bisexual, Trans, and Intersex Association.
