In my opinion, it's not disrespectful to say 'football' instead of 'soccer' in America. The term 'football' is used globally, and it's only in the US where it's predominantly referred to as 'soccer'. While this might cause some confusion, it doesn't really amount to disrespect. It's more about cultural differences and language nuances. Ultimately, respect is about understanding and accepting these differences, not getting caught up in terminologies.
