Don't worry about it. I understand the language barrier, and having lived among diverse cultures, I am also not an alien to very diverging basic understandings of things that others will be offended by. It's just a hurdle to cross, and as long as one is aware that there's work to be done in improving our exchanges with others (don't we all have some), it'll be reflected in everything you say, and go down more smooth.

A good rule of thumb for situations where there's a disagreement see more and a possibility of misunderstandings is to tread carefully, and give others the benefit of doubt. In Finnish we have a saying, "First checking, then whacking.", and the principle seems to work well across cultural barriers.
