Apparently some people think so highly of their own opinion that they get offended by anyone holding a different opinion. Blocking someone for expressing a polite, contrary opinion seems pretty excessive but he can block me too - I don't care.
I'm astonished that someone would block me based on my polite reply explaining that there are different personal tastes when it comes to lighting styles. I responded to what I thought it was a genuine question and took the time to illustrate my answer with pictures as examples.
