The funny thing is I answered this question a while ago. But, to promote Americanism show people that you love where you come from. Tons of people would do anything to live in the country you live in. You can be respectful to others and always have a smile on your face. Flying the United States flag will surely show how proud you are of your country. When the time comes, voting in an election can also show that you want the best for your country. Also when the time comes, you can join the military to protect our great nation.
