I apologize if I'm making you uncomfortable in any way. Having lived in Europe for quite some time, I've come to be acclimated with the traditions that surround me, one such being the engagement and observation of the sport known around here as "football". I understand that in the United States, a very distinct sport that shares the word "football" in its name exists (American Football).
Regardless, the point I'm trying to make is that I'm not making any silly attempts at causing a debacle about what to call "football" or "soccer" as you guys call it. It would just be unwise to be unaware of what the general European populus sees as acceptable and unacceptable when it comes to defining the aforementioned sport.
The majority of European football fans I've met all share a dislike for the word "soccer", and my friend even hits me (sometimes) when I use that word in a conversation. Despite that, American football does seem to have a certain degree of recognition in certain parts of Europe, as several of my close acquaintances/friends have/are participating in rugby, which as far as I'm aware is quite similar to American football.
tldr: I'm one of those Euros* that understand the diverse vocabulary different dialects possess. I've grown up being told to avoid the usage of the word "soccer" when referring to football, thus in my original comment I chose to define the word I was replacing it with beforehand, which happens to be called "football" in Europe.
