Some languages are weird and do not use genders at all. People coming from those languages have a hard time dealing with gendered languages such as English.
Some people do not know what misgendering is, or even what a trans person is, or their culture might not deal with that in the same way your cultures does. Probably they have a different term for it or it is taboo for them to talk about it.
Deaf people are about the same percentage of the population as people who identify as trans. Have you learned sign language? when you approach people, do you consider they may not be able to hear you? Why is this?
There are many groups that also amount to 0.6 to 5% of the population yet are more understanding that the rest of the population may not be prepared to address their needs. Not because of malice or hate but because they simply do not know or they come from a different culture.
