In such a detailed analysis, I felt the concept "Purity test" needed to be unpacked. You seem to speak of purity tests in terms of people being ostracized and attacked merely for having a positive attitude about an altcoin (or stainless steel pans, etc).

But what about purity tests in terms of:

-What people want give a platform to?

-Heuristics for beginners or for quick initial assessments?
