Many people fear and reject what they don’t understand. Many will think poorly of you in life regardless of what gender you choose to live as. Hate speech laws would not change their mind at all nor will jailing them. Both of these things will have the opposite of their intended effect regardless of good intent.
Show people your strength of character and explain to those willing to listen what you think they lack in understanding you. Some will accept you and some will not. Such is life.
Because that someone is not your friend, they are preying upon your fears and using them to turn you into their personal weapon or to benefit off you in some way.
I’ve been down that road and it nearly destroyed my very being and self identity.
But it seems you’ve made your choice and all I can do is hope that you’ll find light to help protect you.
