The reasons are far more sinister than someone's ego. People (not just males) do these things to gain/stay in power or similar gains (monetary, followers, ...).

Most of Africa.

In Niger it's straight up medieval. Hard line conservatives moved in once Sharia hit northern Nigeria, and from the early 2000s to 2010 it changed dramatically. Source: lived there for years. Even affluent gay artists in Niamey with French/EU/US cover denied their sexuality to all but their closest friends. Anything less was a liability. Most did everything they could to leave the region and get to Europe. Once the junta kicked the French out, the easiest safe path went with them.

Even Ghana is bad lately. They buried the country's only skate park in sand because it was "introducing gay stuff to the youth." Laughably stupid, and that was the punt from years of trying to implement a fully draconian anti-LGBT law. There it's easier to blend into Western-friendly parts of Accra, but it was going to end up fucking being hunting parties if that law passed. Source: same as above.

Plenty of other countries literally hunt people down on a rumor. Once saw a police freak out in a SADC county and literal (wo)manhunt based on a couple posting a FB pic of two women at a restaurant.

South Africa might be the only LGBT tolerant county really on the whole continent.

Look at the number of republican gay legislators who pass antigay legislation. Some people are just wired to hurt others.

Yes, it is.

Yu kno de wea!

Islamic "ones" specifically haven't. Some extremist regimes have, especially Christian ones since they're much more common and have done this way more times.

What is the problem is the export of homophobic cultures, not the religion. The religion itself is against using male on male rape as a form of punishment or humiliation. That's what the Leviticus line refers to, that's what the story of Sodom refers to, that's what most cultures refer to when discussing a 'man lying with a man as he does with a woman.'

But some cultures are so homophobic they took the story which was set in a time before consensual sexuality was split into different moral rights and wrongs and they made it about said consensual sexuality.

There are 1.8 billion Muslims on Earth. The vast, vast majority do not live in cultures where homosexuality is viewed as immoral. There are only people that misuse verses and give them anachronistic meanings to fit them to their pre-existing culture. This includes Lot's verse in the Quran which most use to justify anti-LGBT views, which is just a retelling of Sodom an Gomorrah, which we can see above is not about homosexuality.

In many cases across Africa the people that do this are doing so specifically because of Christian Missionaries, even if they later convert to Islam.

So yes, you are indeed being racist when you attack 1/4th of the Earth's population and claim they're all like this.
