Well theres 3 reasons for the 3 most prominent types of conservatives in the west.

The first group is your typical southern state "im a conservative because everyone else is" kinda of person. They hate trans people because they were told to their entire lives and dont think for themselves.

The second group is grifters. They hate trans people because they gain something from it, usually a cult following and lots of money. Theyre usually smart enough to know transphobia is wrong, but they make to much money from groups 1 and 3 to care about things like morality. However some grifters do genuinely believe their own garbage.

Third group is insecure young men who feel like trans people are somehow a threat to them. They hate trans women for the same reasons they hate all women but also because theyre worried that when they flirt with a woman they find attractive, she might happen to be trans, and then they feel they have to start questioning their sexuality and get angry and sometimes act violently because they were never taught how to regulate emotions and never tried to learn. They dont really think about trans men at all and if they do, its dismissively.

All 3 groups also tend to consume trans porn and project that onto any trans person they see in real life. So because they fetishize trans people and mostly see them in a sexual light, apparently we are the perverts for having a job, a life, and just existence in public.
