I feel like so much of it comes from really not doing the work to understand. It doesn't help that With trans issues people get flat out lied to and because there's nobody on hand to say reality check stuff like : "What the fuck do you mean 'The uptick of trans men is causing a wave of hysterectomies in a mass sterilization plot' ... one of the largest reason for temporary detransition is for pregnancies. Also STOP TALKING ABOUT PEOPLE LIKE BREEDING STOCK. " You get a rolling problem where the disinformation is layers deep and they only trust the sources who are financially rewarded for saying the bullshit- because they believe so hard that everything is a conspiracy and have this backwards perception that if only a tiny handful of people in a field are saying something that contradicts a varitable mountain of concensus then that thing is automatically somehow more believable...
I feel like having someone in your family who opens your eyes to the realities because of the immediate demonstratable contradictions of observed reality makes sense. These people caught in transphobialand have by and large been duped. They were ignorant and a bunch of people took advantage of that for financial and political gain. While I can see how not being immediately empathetic isn't great I dunno if I am as mad when observing from the angle of these people just being kind of dumb enough to be played.
Some laws are clarifications of overlaps of other laws that create wiggle room. In this instance the queer panic defense is still being used in court rooms and whether or not it passes as legit is basically up to whichever judge you get, how eloquent the defense lawyer is and how sympathetic to queerphobia the jury is.
If this firestorm of factors does occur you get a situation where there is ruled a legitimate self defense claim because a queer person existed near you.
Trans women experience this way more often than they should just more often then not there's no charges pressed. A cis straight guy approaches them to hit on them (oft times unwanted), they get clocked as trans during the encounter, the guy freaks out and no matter what the trans person does be it reject, deflect or reciprocate, the guy becomes abusive or violent. The thing that the guy is reacting to is his own homo/transphobia, not the behaviour of the trans person he approached. They could be the nicest, meekest trans woman alive who is just trying to escape the awkward situation and the abuse would still happen. There's a lot of people out there who would find the cis guy's reaction way more relatable than the trans woman's experience so that recipe for the trans panic defense still sometimes finds all the nessisary ingredients. The law leaves much less room for interpretation of what constitutes a valid point to argue self defense narratives.
