Speaking as someone who has read the Torah in Hebrew, this is inaccurate. The Leviticus (ויקרא) line is absolutely about 'do not lie with a man as you lie with a woman'. However, we can admit the Torah, and Bible is homophobic and also shouldn't proscribe our daily lives today. 'Reforming' the Bible by making stuff up just supports all the other things the Bible also unambiguously supports, such as slavery and misogyny. And transphobia, for that matter.

From my interpretation of reading the passage, the Sodomites were bisexual, since they would have been happy to rape either the male angels or Lot's daughters. However, the more important point is that they were rapists, and my understanding has always been that they were destroyed for being cruel to guests and the poor (such as the story of a woman giving a loaf of bread to a beggar being punished by being stripped naked, covered in honey, and left to the bees.)
