Interesting video. I've noticed many of these types of people don't differentiate between the concept of gender and biological sex, and often completely ignore the realities and implications of the hardwired biology. As shown in this video, this way of thinking quickly devolves into blatant denial of observable and objective realities. A height measured in feet and inches it not debatable. Its clinical and empirical. It's not an opinion or subjective personal expression. While there are plenty of unhealthy and unnecessary aspects to the cultures surrounding gender (which vary throughout time and around the world,) trying to resolve these issues by denying reality will only cause further problems while failing to get to the core of the issue.
