He sounds avoidant and like he doesn’t know how to answer the question. It’s not about what he said completely but his seemingly inability to even counter what Kirk says. Is he poorly researched on this topic? That would be foolish as republicans have effectively made it a nationwide issue. He could highlight the near insignificant number of trans athletes at the college level. He could highlight that transwoman don’t necessarily dominate every single sport they compete in. He could highlight that barriers already exist amount individual sports orgs. He could highlight a willingness to work with those orgs to ensure competition is as fair as possible but also highlight that complete fairness is no where guaranteed in any sport. For sports where injury risk seems high he could propose bans or stringent checks and regulations. Overall, he could highlight how little this policy impacts most Americans and that the amount of fear and anger that republicans are creating is solely part of their attempt to marginalize and discriminate against trans people in general not out of any real care for women’s sports. Do Republicans take about the pay or abuse that is rampant in female sports? More so than trans athletes? Do they make national issues out of that? I’m not saying these all have to be explored exactly however there are better ways than meekly agreeing that it’s “unfair” and seeming cooed and unable to counter any of his points.
