Men and women are athletically different, down to the DNA.

All humans are genetically different, that is what makes us human. Everyone is capable in different ways. It's best to accept everyone fully and never discriminate.

This is indisputably correct. Men and women are different on the genetic level, even if one is transgender.

Cross competing between genders will be unfair for athletes that have worked hard and are still not better than someone of the opposite gender.

men and women being different athletically is beside the point, athletes no matter gender should be separated by weight class and max strength so that everyone has a fair chance

He is right. They are. They should not compete with each other, and if they did. Men would demolish a biological female any day because of human nature and size difference.

Variation among genders is natural, and the very existence of sports encourages this disparity. People of different races, ability, education, income, and genetics are all equally encouraged to participate in sports, regardless of the fact that all these things make sports inherently unfair. These things could all be seen as an unfair advantage, but these things are natural as well. Transgender people have always existed, and deserve a space in sports. They are not wrong for using their bodies strength to its fullest. The separation of transgender athletes from cisgender athletes is discrimin…  Read moreation, the same way it would be if sports were segregated by race,, height, muscle mass, training, etc. Natural human variation is encouraged, and that standard should apply to trans people. Natural variation occurs in people that are not trans as well, some women have higher testosterone and muscle mass than men. Some people are seven feet tall. Some people are trans. This is purely discrimination based off of the regressive idea that male people are inherently stronger than females. This is also not nearly as much of an issue for trans men in sports, because people don't care when trans people are losing, but now that women- specifically trans women- are doing well in sports they care. This is sexism.
