Nope. People still believe that.
People still believe that God sends hurricanes and terrorist attacks to punish societies that tolerate LGBT people.
People still believe that LGBT people are just closet pedophiles, and equate accepting them with accepting bestiality.
The LGBT community itself has people (TERFs) in it who believe transgender people are just men pretending to be women for sexual gratification.
We haven't really moved past any of that.
"People still believe" isn't a meaningful or impactful argument. You can find at least 100 people who believe virtually anything, because there are over seven billion people and the human mind has much more than a 1 in 70 million chance of believing something dumb.
Many TERFs are effectively identitarians. The unfortunate reality, is that every widespread system which can be exploited, will eventually be exploited. So society needs to be designed with this in mind. Otherwise, one is just providing ammunition to people like TERFs. (Ideological slogans like, "Listen and believe," have probably meant with good intentions, but are epistemologically bankrupt. The same goes for all erosions of due process and innocent until proven guilty.)
Here's a couple of pieces I found in short order:

Who I am attracted to is about what I personally like. It has nothing to do with what other people think is right or not.
that's thought policing and fuck anyone who thinks that shit is OK.
