I'm sure male to female transition would've also been met with more push back as it is perceived as more threatening to the social order. Just like homosexual and bisexual men get more negative feedback than homosexual and bisexual women because male homosexuality is perceived as more threatening to the established order.
Also in this particular case these guys don't have to live in Jamaica. They can go back to Britain when this is all said and done and live relatively safe and secure lives. I'm sure transgender people who have to live in Jamaica have it much worse.
