When someone tells you that you have been offensive, the correct response is 'I'm so sorry'. Not 'I wasn't offensive! How could you think that!'.
When you come to a new place, you need to adapt to the manners there. I don't know what politeness means where you are, but here, your behavior is quite rude and demanding.
And you have continued to tell people what you want them to do throughout the thread. It really comes across as you wanting people to do your work for you. It is very arrogant and demanding.
