The bill, which passed the House last week outlines a framework for dismissing biological differences between men and women.
"I find this to be unbelievably offensive: the idea there is nothing different between men and women," Owens urged, adding that Democrats "don't know what equality is. They don't know what equality means."
"What they are saying right now is that, LeBron James, when he was at high school, with all his physical prowess, should have been able to say: 'I no longer identify as a man, I identify as a woman,' and he should have been allowed to compete against every other woman, and that would have been deemed equal," Owens emphasised.
"They believe in sameness. Making everybody a carbon copy of the others," Owens declared, adding "They hate the idea between male, female, girl, boy."
The best-selling author also said she has been called "a bigot, a hateful individual, a transphobe" for her views, noting that "the left likes to use these pejoratives when you are just speaking common sense."
Owens comments echo those of President Trump who told the CPAC conference that the 'integrity' of women's sports is under threat from trans athletes, prompting frothing backlash from leftists.
