I do fundamentally disagree with the author. People can think poorly of you for whatever reason they want. If someone hates trans people, they can, and you can't stop them. The whole "war on hate" thing was a bad idea; you can't forbid hatred. It predictably didn't work, and it's good that we're turning away from it.
Adding on, the trans issue isn't simple. There are real questions about bathrooms, women's sports, and when medical interventions are called for. Of course, there are also just bigots. The proper response to bigots is not to banish them, ban them, shadowban them, etc. That didn't work. The proper response is -- in the spirit of the new era of free speech -- to firmly state your opposition to their beliefs.
