Does anyone know any controversial poems?

for my project i need to write a parody on a "controversial" poem that i do not agree with. the poem doesn't necessarily have to have cause change in the world, although it would be better if it did. but the only requirement is that the poem was highly talked about or well spread. personally, some examples of things that i don't agree with are war, labor, drug use, animal abuse, violence, certain types of advertising, and things done for the sole purpose of attention, greed, or money. for example if anyone knows a poem that glorifies war so i can write a parody and say all the bad things that happen, or a poem that leaves out the bad side of the story. sorry if im being confusing but please give me poem titles if you have any ideas. thanks:)
