She says for example lefty and a baseball players have an advantage over right handed players in many instances but most experts agree no matter the gender assigned a birth. People have a range of athletic abilities. Evidence that we kept seen.

Cano with Norris joins us now Cain as mentioned earlier Arkansas became the first state to band gender affirming treatments and surgery for trans youth does also complicate things for trans children who may want to play sports. Last Lilly Lindy so in some states and that legislation actually makes it a crime. To provide this gender affirming care to anyone under the age of eighteen now that can greatly complicate someone's transition and it essentially forces them to go through puberty presenting a gender that they don't identify wet. Now the American academy of pediatrics is speaking out they say they highly recommend that young people have access. The appropriate care that they need and this kind of legislation is being considered by fifteen states and it's important to note Lindsay. That does CDC says just 2% of high school students identify as transgender. So opponents of this legislation argued that it targets an already marginalized and very small group of people. And we're talking about sports has the NCAA weighed in on any in this. Last slowly Lindsay so the president condemning this legislation I don't as well.
