To be honest, I didn't even know who the German President was until I read the news just now. >.>

I am not sure if it's saturation or ignorance or whatever.

Saturation is part of it, I think. The other part seems to be ignoring there's a problem at all regarding Gaza. And most of the people I subscribe to are fandom people, and most don't really discuss news/politics (I rarely do myself), so it's no surprise that I haven't seen much of it mentioned here, really!
