Personally, I do not see how socialism is being purported but what I do see is an exercise in creativity.
Creation is the highest echelon of thinking and if students are made to think, create and discuss, I fail to see the problem.
This could be a powerful lesson on propaganda - a la Nazis and the Freedom Writers.
If however, there is a concerted effort to push socialism, then there is a problem.
I think a kid with a conservative background could make a very creative flag - edged with barbed wire, stacked bodies, gaunt faces, long lines.
If teachers can’t discuss the curriculum, there is a problem.
