That's a huge straw man there. The reality is closer to this:

One side: "We should acknowledge trans people and let them live their lives"

Other side: "Yeah, but it seems unfair to biological females to allow trans women to compete in competitive athletics"

First side: "You're denying the reality of trans people, and should be silenced."

First side (actually): "The term 'biological female' reflects a high school level understanding of DNA and genetics. Unfortunately, real genetics is much more complex, and many women who were born and lived their entire lives as women would be flagged by systems to detect so called 'biological women'. Your use of the term is ill defined and unscientific, and any attempt to enforce it is going to hurt both trans and cis women."
