I assume you mean American critics of American participation in the war.
The answer is no, they were not. The environment in 1917 was not the same as December 1941. While German unrestricted submarine warfare disgusted many Americans, it wasn't universally recognized as an adequate casus belli in what many perceived to be a morally ambiguous war.
Just let me know if you have more questions or need further assistance!
