BAD IDEA
If I call someone a monkey, is it racism?
Yes, calling someone 'macaca' is racism disguised in animal form. Don't be that person.
Calling someone 'macaca' (monkey) is a racist insult widely recognized because it dehumanizes and mocks based on race or ethnicity. It reinforces harmful stereotypes and has a long history as a racial slur. So, yes, it’s racism, and you should stop right there unless you want to look ignorant and offensive.
