> So someone having a different point to you is a problem

It's not a different point. It is you disagreeing with an indisputable, easily verified fact. There is a difference between "it's a bit chilly today" and "it is snowing in Ecuador right now".

> It is totally polite. I ask for a context and said I was open. Wow.

No, totally polite may have been something along the lines of "Oh that's interesting, I didn't know that. Do you have an example of its use in a regular game so I can familiarize myself with it a bit more?" But even that is showing a lack of willingness on your part to look for yourself before asking others to do your research for you.
