Of course, the UK and US are different, but the findings are statistically significant and certainly merit duplication within the US. Think about it: The number of people who are trans or have family members or close friends who are trans has been estimated to be between 11 and 21 percent according to PRRI and KFF. Of course, one need not know any trans people to be a very strong ally, so the percentage of Americans who have very strong pro-trans views could be quite considerable.
