Unfortunately in a lot of cases fear does work. You have to remember that most people don't really know much about trans people, after all many think of it as gay pride not lgbtq2+ pride.
When people only hear bad things about trans people that affects their opinion, it's not even mostly malice for a lot of people just ignorance.
Thankfully we have allies spreading the truth about us and hopefully more correct information will start to spread more reducing the effectiveness of trans hate.
Also thankfully the new generations growing up are far more tolerant than even my own generation, gen x.
