Probably I would be transphobic, unless I had a closed loved one who transitioned or was trans, and felt there pain. You got to realize, perception is shaped by your values, environment, culture around you, without having direct contact with someone close to you who is trans, you may have negative perceptions of a set of people, it also depends on your education, in the social, psychological, anthropological sciences, medical sciences(ie.even then some of the latter are prejudicial), sans hard sciences, unless you or someone you care about is trans. I still see prejudice towards gay, lesbian, bi, other ethnicities to this day, sad to say.
