I knew/know what you were saying.

Don't worry, I was just "ribbing you".
What I meant is ... the way I read it (by your saying "and while that is correct"), it looked like you were saying that it is correct that an albino has to be white or anything that's white is an albino. IOW Contradicting yourself by indicating that this belief, of many people, is a misconception but, then, in the same breath, saying it is correct.
Ah heck, I am, probably, not giving a good explanation soooo ... let's just say that we can chalk this up to an ill-fated attempt at friendly "ribbing".
