Are the 144,000 men that are "not defiled by women" homosexuals? Are only gay men to be saved? 14:1-4

"The abominable"
John isn't talking about the snowman here. According to Robert Gagnon (The Bible and Homosexual Practice: Texts and Hermeneutics), it's homosexuals. "The reference to 'the abominable' (ebdelygmenois) matches up with 'dogs' in [Rev] 22:15."

"Dogs [homosexuals?], sorcerers, whoremongers, idolaters" and along with anyone who ever told a lie will not enter the heavenly city.
"[T]he term 'dogs' in Rev 22:15 primarily has in view emasculated male cult prostitutes, without excluding a wider reference to any who engage in homosexual practice." Robert Gagnon (The Bible and Homosexual Practice: Texts and Hermeneutics) 22:15
