CC does not share(and does not have access to) my personal thought, opinions and other things than can affect my employment that I might want to share anonymously.
I am not sure what is hard about this distinction to grasp, why would it matter if CC shared my email if I share my email on my own websites?
I need your email address with your real name to prove that you are not a bot.
This is strictly needed for throttling reasons, your email address will only be temporarily stored in the volatile memory of the device.
(If you think there is anything wrong with this then you do get the point and silence speaks louder than words)
