Which of these scenarios sound more credible to you?
A: Joe Biden, a man who turns 80 later this year and has been a politician his entire adult life, got through the 2020 election while hardly broaching trans issues at all. Then, once elected, he realized they were the most pressing issue of our times and staked out the leftmost position.
B: Biden has no clue. "Affirmative care" and "gender identity" are just syllables to him. But he knows he has to say them right to make big Dem donors happy.
Given the choice I'd put my money on B. These people are in customer service, except that only a narrow group of Americans form their customer base. Actual radicals in the administration are probably few and far between. But they have the advantage because they just have to work around empty suits.
