Yes people keep saying that. However it is not an argument that should stop the debate. The difference is that palm oil production has a lot of issues due to the location: wildlife like orangutangs is killed, old rainforest is deforested, native people are displaced, and it occurs in very corrupted countries (Malaysia and Indonesia). While for example rapeseed oil production requires more land we don't for example here in Norway have those same issues with production as palm oil.
