What I figured out on my trek in life, required me questioning my masculinity at a very core and low level. Through therapy (won't go into the dirty details), it became really easy for myself as a CIS Male to see transgender women as 100% women.
My honor badge which doesn't come close to the mental hellscape that transgendered folks go through , was dealing with dual traumas and upbringing issues in my traditional household.
So I agree whole heartedly with this view, and trust me what you have to go through to peak into the cracked door is not worth the price of admission "and" the only answer IMTO is to say I am here for you what do you need to feel safe and secure.
