Welcome. Yes, there is a high sensitivity category in the insult-offense matter. Some people don't even need words to find offense. Just look them in the eye and risk a threat or blow. Don't know what moves them.
'Political correctness' is also present in the world of jobs and professions. Cleaning ladies are hard to find. You have to look for 'interior caretaker' ( at least in my country) The word laborer is gone completely. It moves from production cooperator to production assistant. No garbage man but environment-cooperator, etc.etc.
