In Germany the original Wolfenstein used to be kinda illegal (there is a sutle difference which is not the point here), because of the "fascist propaganda" facepalm. Still... It was the first 3d shooter I had and I mostly shit my pants, because I was 6 years old xD
You forgot to mention the author of that quote: Abraham Lincoln
Just looked it up for Germany: over residential areas you need either "an explicit permission of the owner", or "it is very light (<250g) and has no ability to record video, audio or radio" or "it is more then 100m above ground, not in the night and some other fingerprint" [1].
In all EU you actually need a registration on your some clearly visible [2].
So, of they are below 100m or in the night, just call the authorities. If you live a bit outside it might just not clear from above that it's private property.

On some mobile Screenshot editors the scribble tool is the first to see, and apparently easier for some PPL than the crop tool,
I was actually more referring to the chart implying that low oxygen means higher concentration of toxic gases
Altitude reduced the density of air as whole. The graphic is about changes in composition while density should remain similar, meaning if oxygen is low, something else (e.g. carbon mono-/dioxide) is high. So I wonder how this compares.
Please stop calling them Nazis. That would mean they are social, which they are not. They are just capitalist/plutocratic fascists.
I guess there are actually PPL who don't know what gay means originally
My math teacher in high school always said "math is 90% looking" and if you didn't get the task directly: "look again" ... Funny part is, that actually worked for most of the class xD
If it's so well known, the configuration should be trivial ;)
