As to the first question:I do not think that is what he is doing at all. Just like the pro-life movement (at its best) does not attack the women who have had abortions, but the culture of death that makes it possible. 

As to the second two:Great questions! You sir/madam have unleashed my inner philosopher. Be warned. Transgenderism is the identification of a gender different from one's assigned sex (can include surgery, but not always). I think the ideology that grounds transgenderism is a disregard for the value and meaning of the body. Today we often understand the body as a mere "possession," that can be changed, manipulated, mutilated, and even disposed of (as in the case of assisted suicide)  at will. However, the Catholic understanding (coming from Aristotle) is that we do not have a body, we are a body. The human being is precisely the combination of soul and body. Our body thus has an inherent meaning/value to it which elevates it above a mere possession
