Absolutely - although their story is not listed as an example to follow but a demonstration of how far they had fallen because of the culture Lot had raised them in. In other words, the story of Lot's incest is included in the Bible to warn G-d's people of the consequences of the "consenting adults" theory.
What two consenting adults do in the privacy of their own home is immaterial to society. What they do when they discover they make up a special interest group is very material and must be stopped.
Shalom.
