If you take a strong argument and through in an extra weak point, that just makes the whole argument less persuasive (even if that's not rational, it's how people think).
You wouldn't say the "Uyghur genocide is bad because of ... also the disposable plastic crap that those slave factories produce is terrible for the environment."
Plastic waste is bad but it's on such a different level from genocide that it's a terrible argument to make.
