Answer: No, the critics were not Anti-Americans.

Explanation: Critics are professional commentators who comment on a particular event or view point. They are not necessarily affiliated with any particular ideology. Thus, the WWI critics were able to asses different consequences of the war and they deducted that WWI did not fulfill its very purpose rather lead to inhuman slaughtering of masses, even those who were innocent and were not involved in the war by any means.
