The "Three Red Banners" was an ideological slogan in the late 1950s that called on the Chinese people to build a socialist state.1 The slogan consisted of the General Line for socialist construction, the Great Leap Forward, and the people's communes. After the first Five-Year Plan, the People's Republic of China continued its socialist construction by introducing the "Three Red Banners Movement". The Three Red Banners Movement was an ideological slogan in the late 1950s that called on the Chinese people to build a socialist state.0 The Three Red Banners in Joe Biden's logo represent the branches of government and the strength of unity with Biden.23 The designers of the Biden logo had specific reasons for the three red lines in the "E" of the logo, which are a representation of Biden's investment in America.

I think it's more that three is the minimum number of objects required to make a series, and minimalist logos are still all the rage (will be interesting to see if AI cements this or flips it). So, three stripes and three stars to evoke the American flag without using all 64 visual elements of the flag.

I don't think we should give up one of the most natural and obvious ways to incorporate our patriotism into easily-digested designs just because a version of a foreign government that was replaced by an actually effective governing ideology 50 years ago used a common number of a common visual element in a common color 70 years ago.
