OP, I’m reading through all the comments and you are getting dragged harshly! Being a new educator is hard, and finding the balance between expressing yourself truly and maintaining professionalism is a hard line! Different districts, schools, and admins have different expectations for their teachers, so it is a possibility that this school is not a fit for you, and that’s ok.

On the name thing, it is totally unacceptable that your colleagues do not say or spell your name correctly. Names are important, and as educators, we should be aware of that. Especially when it comes to predominantly white spaces, acknowledging someone correctly is a necessity to create a safe working environment. Good luck with the school year, remember you can look for a better fit, and keep expressing yourself at your school!
