What you are saying, and what should be done in every aspect of life, is that you are free to say what your own beliefs are as long as you don't try to promote them or push them on others, and that you shouldn't say anything negative about another persons beliefs.
Or in short: Be polite!
The way I interpreted this topic, Sebastinos, was that we should say what we believed personally, not comment on other people's faith (or lack thereoff). As mentioned above I don't believe in a God, though there are times when it would be a comfort to have that kind of faith...
I have nothing but respect for other peoples way of life.
