The majority â 70 percent â of Americans explained the reason they did not regret opening a store credit card during the holiday shopping season was because they received a large discount on their original purchase. Although shoppers may feel bullied, they are also sympathetic for the position the store clerk is in.
The adults polled estimated that 25 percent â one quarter of all Americans â are gay or lesbian. According to Gallup, over half of Americans (52 percent) said that at least one in five Americans is homosexual, and 35 percent estimated more than one in four. Only 30 percent estimated under 15 percent.
