The problem with this line is that it becomes an argument against me, rather than self education. There are many comments about this on this very post, and it's recent headline news!

The reason I asked in that way was to see if GP actually knew anything about what they had strong opinions about.

On the other I think asking someone for a citation to their rather strong claim isn't incorrect. Digging through unstructured HN comments isn't my idea of a good time and being sent off on a treasure hunt by fellow commentors isn't why I come to this website. Collaboration is how we move forward!
