Some websites I go to using Chrome, there is a comment section in which you can post with your facebook account. Under it, it says "Facebook Comments Plugin".
For some bizarre reason, this comments plugin knows my facebook account. I consider this to be a tyrannical invasion of privacy, so I want to remove it.
However, I cannot find a "Facebook Comments Plugin" in Chrome (Chrome by the way has removed "chrome://plugins"). I'm not even sure if it's in chrome. I suspect it is in the website itself.
But if it is in the website itself, how does the website know what my facebook account is? Does this mean Chrome complicit in the conspiracy? How otherwise would the information get from facebook to the website with the embedded FB plugin? How does the website know that my facebook account has been accessed with my browser?
This tyranny needs to stop. How do I remove those sites' ability to know my facebook account?

this comments plugin knows my facebook account
Yes; its HTML and JavaScript are hosted from Facebook's servers on facebook.com, and hence have access to your Facebook cookies.† (It's not a plugin in your browser, but it's embedded in the web site you're visiting. You cannot uninstall that, but you can use a browser plugin to block it.)
how does the website know what my facebook account is
It doesn't. Only the embedded comments section on that webpage knows; a sane browser (including Chrome) will not allow the website that embeds that section to access any of its details.
† So yes, Facebook knows which web sites you're visiting, for all sites that include some Facebook widget, even if that's only the "Like" button. Stop using Facebook if that bothers you, or at least install something like Privacy Badger.
