If the U. S had not been involved in WWI, do you think German culture would have had a bigger impact on America today?

yes.

Explanation:

I think this because of the placing of countries on the map it would have been arranged as U.S & Germany as the main leaders of war and England France and Belgium behind as their backup team. You ask how? this is because Germany and U.S would have started another war and would've beat the eastern side of the world and the countries would have been different placed as Germany would have taken over China or Russia then there would have been no more wars ever between the eastern and western side again so that means that Germans would have a bigger impact.

I'm so sorry if that doesn't make sense summarise this in your own way if you would like to use this example :)

freedom of speech is also protected by the 1 amendment.

explanation:

here is pretty much what the 1st amendment says:

congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
