Why do men, who are attracted to trans women, treat us so poorly?

Basically the title. Do men really feel that embarrassed to claim us and date us? In my and most trans women's experiences, men tend to only view us for one thing, and would never date or marry us even if they would prefer us physically, emotionally, etc. Is it because of shame from family, friends, society? All the above? Whats the deal yall...
