I know where you're coming from, but it's not like that at all.
The only thing that makes people thing 'sage' means 'fuck you' is because you let them.
How?
Because of this shitty board mechanism that highlights your name in blue everytime you sage that announces very brightly the fact that you sage'd.
Sage's should be private and personal. Sage should be to post without bumping. Not for making your name blue with a mailto:sage link.
