I never implied that, I'm amused at how polarized my comment is, where did I imply that? You can live your life any how you see fit, you don't ever have to code afterwork or touch the computer. I'll just be suspicious about your ability until you prove so
I think it is fair enough that in order to judge someone's competency you need concrete evidence of their ability, I completely agree with you there. Side-projects are useful for doing that, but there are other ways as well.
It is entirely reasonable to provide programming tasks or whiteboard interviews or whatever in lieu of going through someones personal project.
Using your own lifestyle and tastes as a benchmark is what riles people up. If side-projects are the measure of the man, then there is an expectation of how people should spend their free time.
I believe the polarization is coming from how this is expressed, specifically pegging side-projects as the determining factor. People can find joy in their work (programming in our case), but not necessarily want to do the same thing in their free time.
This is likely biased as it is coming from someone with no personal projects though :)
