I used to work in adtech and the most we could do was track locations. Even that didn’t work properly for our purposes because most shops are in malls where several different stores co-exist on the same coordinates. It only worked for outlets in retail parks which were separated from one another.
I think this would be less surprising if we didn’t imagine LGBTQ people were one homogeneous block of political beliefs and opinions. Some of my most right-wing friends are gay.
