In general, you're free to call the system "Linux" if you want to. You can even do so in public. That's treating us unfairly, but you are free to treat us unfairly if you insist. We won't try to stop you, we will only say it is wrong. See http://www.gnu.org/gnu/gnu-linux-faq.html#whynotsue.
However, this list isn't a general public forum for people of all views. It was set up by the FSF for discussion among people who support it about how to carry out its work. If you firmly disagree with an important FSF decision, you have a right to your views--but you shouldn't use this list to argue against or defy our policies. We have another forum for that sort of discussion--the newsgroup gnu.misc.discuss. Please take it there, not here.
