AFTER READING YOUR ORIGINAL POST, OTHER RESPONSES, AND YOUR SO WHAT HAPPENED:
You may have become your "own worst enemy", your language and what you said what happened and then said "what bacisally happened" indicates that what actually occurred in you review, is questionable. "Supposedly" is never something you can hang your hat on. If you take the next step outside the company, you will need to have documented proof other then your original post. The fact that you sent out an email to all your co-workers will ONLY work against you.
AFTER READING SOME OF THE OTHER POSTS:
Absolutely DO NOT send any email at your work place talking about this matter. If any actions needs to take place it should be by HR or management. Don't fan the flames.
How was your review?
Did you hate your "freakin job" before your review?
How long have you worked for the company?
What was the answer to your question, "Were they get off asking such a thing"?
If you are thinking of quitting your job and filing a law suit (private or EEOC), please be aware this could take a very long time and depending on your company's legal capability, you could lose.
My advice is do not quit your job, go to HR and report what happend. Contact EEOC and file a complaint with them. Document everything that happens from now on (dates, times, incidents, people etc.). If for some reason you are terminated, you will at least be eligible for unemployment.
As long as you are doing a good job and not taking part in the gossip,lies etc. that your co-workers are doing, you have no reason to feel bad. Stand up for yourself.
