Americans who have a close personal relationship with someone who is transgender (a close friend, a family member, or they themselves are transgender) are generally comfortable with learning that a friend is transgender (62%). Americans who have an acquaintance who is transgender are similarly likely to say they would be comfortable learning a friend is transgender (57%). Around one-third of Americans who do not know anyone who is transgender (32%) say they would be comfortable learning that a friend is trans.
From the survey itself which the article linked to. https://www.prri.org/research/the-politics-of-gender-pronouns-and-public-education/
This poll seems to have managed to confirm that people who are not transphobic are in fact, probably not transphobic.
Amazing.
