I see all these posts all the time about Libras faking the funk and being passive.

I'm actually pretty aggressive at times. Any other aggressive Libras? I actually have zero ability to hide my emotions. Its written all over my face. All my friends tell me its actually worse when I try to mask my feelings. I am not rude, but I am assertive. I actually know quite a few the same. Why do we have this fake reputation?

the fake reputation is being aggressive while pretending you're not, befriending people for purely material gains or social advancement, that type of thing.

My best friend is like that. If he truly has a problem with someone he will say it out in the open to their face, perhaps in front of other people. Also he doesn't hide his emotions or opinions. Maybe it's the Cancer moon, but even with that being said ive never met a Libra who was afraid to tell people what they think.
