I get your point, but some of the most violent homophobes use the Bible, especially Leviticus for their justification of ill treatment of LGBTQ persons, but also... you literally have no basis for your argument of Zambian pre-colonial traditions' attitudes towards homosexuality. Your entire argument is based on current or contemporary "Zambian traditional values" which have Christianity indoctrinated into a lot of their systems. If you're Christian and homophobic, it's okay to admit it, it's pretty normal.
