Regarding transgender research: Like I said I'm socially liberal. Gay marriage, cross dressing are personal choices. But during the Biden administration this transgender business became institutionalized. With a horror show of men in women's locker rooms, school bathrooms. Gender identity:,* if personal fine but this became political and caused legal issues.
The DEI movement began years ago. If i's a man's world, one could say as early as the suffragette movement around the world. Here is an expose, mainly British orientated. Relish the fact that 1000's of women were imprisoned for support of the cause. Nowadays, hardly anyone gives it a thought that woman should have the right to vote. *

Note that here again the discrimination based on race, gender (male/female), religion, ethnicity, creed, disability, colour was not a valued social contract with members of society. At that time, when these became enshrined, a company may have listed itself as an Equal Opportunity employer. Everything fell into place and life went on.
With the present DEI concepts ( which, depending upon ones outlook, can be considered ill-advised, or a natural progression of rights and compensation for past wrongs of your grandfathers ) Biden has little to do with it. A President of the times, although the Democrats, Trudeau Liberals in Canada, and many other governments around the world do seem to have embraced the principle, which as you say ' became institutionalized'.
As for the transgender business , any questions on whether what is being done correctly could/would have one labelled as transphobic. For example, the question of administration of puberty blockers or surgery for minors, and advice given to parents with a troubled child taken in for diagnosis - no decent studies, but an experiment upon a young population of troubled teens, or younger . ( I do take Elon Musk at his word that he was lied to by the 'medical team' - thankfully it seems the daughter seems to be OK herself with her acquired gender ).
Had these social movements( not just the transgender ) been done with a little more thought, and with less aggression, less aggressively, less arrogantly , then it could quite be that cancelation of DEI, and the executive order of only 2 genders ( rather than 200 an counting, including animals ) would not have occurred. Usually its the whole that pays the price of just a few stupid loudmouths that want their way.
* Please note that within the Maga crowd, or it could from Project 2025, there is a few stupid 'loudmouths' ( but not so loud as to cause consternation ), that a woman's role in society, is for childbirth and raising a family, though having not thought through diligently themselves the implications, repercussions, and associations
