And do you feel that address people by their preferred pronouns is one such area?
As mentioned in an earlier post if someone asked me to use their preferred pronouns then I would do so.
You do know that a trans woman isn't just a man in a dress, right? If they are taking hormones, then the effects of those hormones pretty much removes any physical advantage they would have had.
It is not as simple as that. Hormones is only one part of the physical side of gender. It does not remove genitals and many transgender women do not want to go that far. In fact some do not want to even use hormones as they can have bad side effects like making a person sterile and causing cancer in some cases. So there is a range of physical states that a transgender women can have. But like I said If a person can transition completely somehow in the future then I guess they have physically changed themselves to the opposite sex as well.
"As Joanna Harper explains, "Once a trans woman starts on antiandrogen drugs as part of HRT, then her testosterone levels quickly fall to female norms. This is followed by a rapid reduction in the percentage of red blood cells in the blood stream, again to female levels. The lower hematocrit levels have a dramatic effect on endurance sports such as running or cycling. The lower T levels also will cause muscle mass atrophy. The loss of strength is not as rapid, nor as complete, as the loss of endurance, but trans women will lose much of their strength advantage over cisgender women.""

That does not account for transgender women dominating women's sports already. If they are dominating then they must have greater capability not because they are a women but because they are a male presenting as a women. The problem is most transition after puberty when the main differences from males and females kick in such as males having larger bone structures, more muscle mass, bigger hearts, lungs and greater respiratory and blood circulatory systems. Some transition after already developing as a male athlete so they have developed their bodies to maximum capacity as a male. Hormone replacement therapy will not reverse most of this as it has already been developed. But sports is only one aspect of the physical side I am talking about. There are other implications to do with women's privacy and medical situations as well where biology is important.
What about mental disabilities? A person with a mental disability literally feels that way in their mind, just the same way that a person who can't walk feels that way in their legs, for example.
But we have tests and diagnosis that will determine that mental illness so we can know what the conditions are. So someone with a mental illness may think they are hearing voices but we can know that those voices are not really there are are only in the mind. At the same time we would not say that those voices are real and something to encourage as they have no basis. Just as we should not encourage people to take hormones immediately and get surgery to change their physical state because a state of mind is telling them they are the opposite sex. We should seek therapy and perhaps allow things to sort out as most people will realign in their minds with their bodies.
And there are literally zero DNA markers for ethnicity.
"Genetic methods do not support the classification of humans into discrete races, [and] racial assumptions are not good biological guideposts. Races are not genetically homogenous and lack clear-cut genetic boundaries."

Of course there are markers for ethnicity. Many people such as those who use Ancestry.com have done DNA tests to discover their ethnicity. It may come back that a person is 60% Italian, 20% Spanish, 10% Scandinavian and 5% British. Some have even shown people are a small % Neanderthal.

The article you have linked is about race and not ethnicity. They are saying that race has been attributed certain traits like people who are black have certain behaviors and those who are Asian think a certain way based on social and cultural constructions which I agree with the article. That can foster racism. But ethnicity is different as it is about heritage such as being Italian because they had an Italian parent. But even race has certain physical aspects that cannot be determined by social construction like gender. For example we can tell what race a person comes from to an extent by their physical features such as a negro with negro parents is usually darker skinned. A person with dark skin cannot claim they are a white person if they feel they are in their mind.
There is a huge amount of evidence that the physical construction of a person and their sense of gender are two very different things.
Yes I agree, gender use to be determined as a social and cultural construction and that was fine by everyone a decade ago. But suddenly there has been a change and now people say that the way a person feels is the only way we can determine gender and that the physical aspects have nothing to do with it. Science shows that biology is part of gender and affects the way a person experiences gender as well. It infiltrates every cell in our body.
