Even though I am not a newbie when it comes to information sharing, I have to admit that some terms tend to tease my imagination and increase confusion. Well, I am averagely educated and I like to advance my learning actively or passively but still I find I am not in the right pace. Recently I was reading an online article and learned about this "new gender" term which is undoubtedly trending. Among the many definitions given, I still find my hunger to know more about it increasing. What is New Gender? Any idea?
