step 1:The way that amendments have affected Americans' participation in government is by guaranteeing their rights and freedoms 18-year-old given the right to vote, nineteenth which gives African-American males the right to vote.This amendment will protect people from ever being used as slaves again in our country.
step 2: My idea for a new amendment would be equality for all regardless of race, gender, nationality, religion, etc. This amendment would protect all citizens from being mistreated.
