The most "sexist, homophobic" church I ever went to was a Pentecostal one. Woman were strongly encouraged to wear skirts/dresses and cover their heads. Homosexuals were encouraged to be excorcised or leave. It was mostly black people which probably kept the church from being scrutinized in a big city in Massachusetts.
I had to leave because as I got deeper I found they harbored some significant heresies in doctrine.
It's relatively little known that perhaps 1/4 of Pentecostals, like the United Pentecostal Church, are "Oneness Pentecostals." Basically it's a form of the ancient modalist (Sabellian) heresy. They can be fiercely anti-Trinitarian.
