Only people who are siloed think that this issue is one of triggered conservatives pitted against liberal thinkers on the right side of history. As I've repeatedly detailed on this thread:
1. Rates of trans identification have gone up by more than 1000% over the past decade or so. Don't believe me, look at the stats from England, Finland, and other countries with national healthcare. Many are concerned about the harmful medicalization of gender nonconforming people.
2. This issues is also about whether society values subjective reality more than material reality. It's one thing to allow people to live their lives according to their subjective values (as long as doing so doesn't hurt others) and asking other people to agree with your subjective values. When the government backs up this stance, we're dealing with totalitarianism.
3. The belief that an inner sense of self, "gender identity," overrides biological sex and makes one a proper member of a sex category is transubstantiation. That is a religious ritual attached to a religious belief system. When institutions absorb this belief system and impose it on the people, they are effectively forcing religious beliefs onto nonbelievers.
***This point frustrates me the most. I've been on the left for my entire adult life, and I cannot stand the hypocrisy. Some believe that bigoted Christian conservatives are out-of-touch with science and reality and that this prevents them from understanding the "truth" that trans women are women. They truly cannot see that they are the ones with religious beliefs.
4. We're also talking about an erosion of first principles. Biological sex is the basis for countless laws and social conventions. Now, multiple public officials have refused to define or acknowledge biological sex. When we're talking about the dismantling of the basis upon which several aspects of our society (and nearly all societies across history) are based, it doesn't matter whether there is one Lia Thomas or 10,000.
5. I understand that some men don't care about women's sports, but I cannot fathom how anybody could make the argument that men who are agaisnt Lia Thomas competing "don't care about women's sports." I cannot count the number of times I've seen men, who are good but not great runners, pace women who are slower than them but elite among women. Friends, boyfriends, husbands, coaches...many contribute to women's sports all the time. Go to a marathon that has OTQ pacers for women. They're usually men.
6. "Inclusion" is sometimes unfair and harmful. Ask yourself why nobody is trying to make the paraolympics more inclusive. Excluding people who are able-bodied increases the opportunities in sport for people with disabilities. Females do not have testes, and therefore, do not have access to a suite of advantages that males have by virtue of their bodies.
7. This movement is blatantly misogynist while fronting as progressive. It's an emotional shakedown that exploits people's natural compassion, especially the compassion of women. These are well-known techniques used by abusers to extract material and psychological benefits from them.
8. It's possible to create policies and values that improve the lives of gender non-conforming people and trans people without upending reality and resorting to totalitarian tactics.
SUMMARY: The issue is much bigger than Lia Thomas. Ask yourself whether you'd feel comfortable stating the fact that Thomas is a male in public. We've reached a point where people cannot make factual statements without being censored, shamed, and/or losing their jobs. This is the stuff of cults, gulags, Maoist retraining camps, not liberal democracy. This is the most frightening, disturbing stuff I've seen in my life.
