As a cis male I don’t feel the same level of apprehension toward trans males as you relate. I don’t feel revulsion toward their pre-op lack of male genitalia. I think the difference is that my fear of women is much different than your fear of men. I fear the scorn and rejection of women so I would never seek to reject one struggling with gender identity. You seem to fear for your personal safety around men so it seems appropriate to be wary of trans women.
