I think the main reason for anger toward cultural appropriation is that, for example, black features were suppressed and disrupted for years and many people assume that this cultural appropriation being shown is a matter of 'dress up' and turns their cultural significance/history into something playful. Many people (especially those who are white) are adopting these features or styles and not receiving the same backlash that many poc receive, even in modern times.
That said, I'm white and therefore cannot define/determine exactly what cultural appropriation is, because I was lucky enough to be part of a race that hasn't been oppressed for hundreds of years.
EDIT: Also wanted to add on that it really annoys me when people who AREN'T poc start arguments about what they perceive to be cultural appropriation, because it makes the reality more easily dismissive as people can then call them "snowflakes" because they're calling out everything and everyone. Leave it up to the people with the history of discrimination to decide.
