English (like most languages) has three third person singular pronouns: 'he', 'she', and 'it'. Other languages even have gender identifying second person pronouns and gender identifying plural pronouns. English seems to have gotten jipped on the supply of pronouns. If you do not understand our array of available pronouns and their correct usage, then you obviously do not use language much.
We often apply 'he' and 'she' to non human objects, however we balk at apply 'it' to people. In fact, in most other languages each object has actually been assigned a de facto gender. English is perhaps the most gender neutral language currently in use.
We get all uppity about people referring to themselves as 'we' because it makes them sound elitist due to the historic habit of royalty using 'we', so why should we let people incorrectly use 'they'? 'They' implies that there is more than one of you. The misuse of 'they' as a gender neutral person is a terrible abuse of the language.
The fact that our literature and fiction place so much emphasis on the usage of 'it' to refer to a dehumanized creature is telling about how much importance our culture places on gender. If it is now culturally acceptable to not have a gender, then it should be acceptable to call you 'it' since the removal of the gender is no longer offensive as gender is no longer a required trait of being human.
If you have no gender and don't want to be called a 'he' or 'she', well we have to call you something so 'it' is the correct choice (unless there is more than one of you). You can't both be offended at me applying a gender to you and then offended when I don't.
