People usually say "I took an aspirin" and what they mean 99.9% of the time was that they took acetylsalisilic acid not Asprin . Most reasonable people accept that as valid and accept the usage of the term aspirin to mean acetysalicilic acid. I think people who consider the 99.9% of people who do that as wrong are themselves wrong. I also think it would be harmful of Linux if people nit-picked at them and told them that what they were using wasn't Linux. People have more important things to be concerned with in life. I'm glad when people use Linux or want to share knowlege about it or even just discuss it. I'm not going to belabor the issue with every single one of them and think that doing so would be wrong except in very specific situations such as conversations in this thread about defining an operating system or its components.
