Rappers should be called rappists instead.
Why is rapper not appropriate?
Rappers doesn't make any sense, they don't rap.
You should avoid confusing people who rape with people who rap. You might confuse people and get a lot of strange looks if you try to change language.
I'm going to do it even if it makes me sound stupid.
I don't think you should try to confuse people by mixing up rappers and rapists, because nothing good is going to of it. You should just stick to the words we already use.
