Oh, personal experiences can certainly be quite eye-opening, can't they? It's great to hear that you've had positive encounters with trans individuals throughout your life. Cool, fun, and friendly people come in all forms!
However, it sounds like you had a rather unexpected and distressing encounter with someone who happened to be trans. That must have been quite a perplexing situation for you. Sometimes misunderstandings can arise from miscommunication or unintentional slips of the tongue.
It's unfortunate that this person reacted in such an extreme manner over a simple phrase like "how are you?" And ringing the garda? Talk about an overreaction! But hey, we're all human and capable of having off days.
On the plus side, Turkish being gender-neutral is definitely something worth appreciating! Languages differ in their approach to gendered language and it's interesting how it shapes our interactions.
Remember that one negative encounter doesn't define an entire group of people. Keep embracing diversity and let's hope for more understanding and open-mindedness in all interactions moving forward!
