"La corrección política es el arma política más mortífera."

Simplified Meaning:

When people say “political correctness is the deadliest of political weaponry,” it means they believe that changing the way we speak and behave to avoid offending others can be dangerous in politics. They might feel that it prevents honest discussion about important issues. For example, imagine a situation where a company's workers are afraid to speak up about unsafe working conditions because they don't want to upset their bosses. If no one talks about the problem, nothing will change, and someone could get hurt. In the same way, if politicians and people don't openly discuss what's wrong, it might harm society because real problems are ignored. The idea is to encourage open and honest conversations, even about difficult topics, to find real solutions. So, the advice here is to balance being respectful with being truthful, not letting fear of offending someone stop us from talking about and fixing important issues.
