Schools will now be free to discriminate against these young people (details here).
The new education secretary, who has a history of being anti-LGBT, actually wanted to keep the rules in place. But powers-that-be inside the Trump administration overruled her, including the new Attorney General.
Now some people still insist Donald Trump is pro-LGBT, but this action reveals two interesting facts: First, more moderate voices within the administration that wish to accommodate LGBT people are being silenced. And second, the claim that Trump is pro-LGBT is directly refuted with actions like these.
Perhaps when Trump waved that upside-down rainbow flag for a few seconds, he thought he was summoning a leprechaun.
