The biggest issue I have with your points are you can apply that same logic to all kinds of absurdity. Pick one or create one and it applies.
I also disagree with you that it is a healthier mindset to believe in essentially an unlimited amount of possibilities (unlimited because you can't define an unknown in this case) but whether something is healthier or not is not a factual statement. It is just a subjective statement that is based too much on the individual and the mental status of that individual to determine if it is healthy or not. I could argue that it was unhealthy to believe in what I used to believe(specifically evangelical/Protestant Christianity) because of my underlining condition of dealing with obsessive compulsive disorder and depression, but that claim of being unhealthy doesn't hold much weight because again, it depends on the mental state of an individual.
For myself, yes I am an atheist and yes if I come across evidence that convinces me differently then my views will change, but that doesn't make my current stance any different or say weaker as some weak atheism(I find that term laughable), especially when I don't have the knowledge of what that evidence would be to convince me.
Also remember, theories are believed to be true until proven wrong when it comes to science. The word theory is used differently in science then in colloquial type of discussions. So for example, just because we believe the theory of evolution is fact, that doesn't mean we think a creation story myth is possible because we use the phrase, theory of evolution. I bring that up only because, the fact science has changed in the past doesn't mean we can't believe our current understanding as fact.
The word atheist is just a term for a rejection of a specific proposition. There's no reason why that would logically need a purpose. We find purpose elsewhere.
If your a chess fan, Scid vs PC is regularly updated and it's hosted on sourceforge. However I don't go there unless it's for that or other related projects.
Dust0741 my apologies. As others rightly pointed out I didn't answer appropriately and deleted the postt.. You won't be able to get the latest kde on Debian. You could look at Sid or Testing but I don't know if they ship that. I dont use Sid or Testing so I couldn't help you if they do.
Download the official iso, get it to a USB stick and install it. You'll be able to install KDE during install.
I love Debian. I think it's history and how major distros use it as their base explains more than I could about why it's worth a shot.
If you find out you don't like it you got a bunch of other distros to choose from.
For me it's the ability to use my hardware as long as I want after a tech company's EOL. When I was on Windows 7 and it reached EOL my machine was unusable. Couldn't go back because I waited to long. Then I updated my machine and Windows 10's EOL was set and again, machine will be not be safe to use. I switched to Linux before that release date but the way Microsoft does with these EOL dates, for me isn't sustainable. I dont need to buy a new machine every few years. I want my machines to be a usable and secure for as long as I want it to with minimal impact to my finances and stop simply just throwing old machines away. And if I run into a distro that my machine isn't beefy enough for, I have distro-hopped around enough to be able to go to something else but still be in the Linux-verse.
The stuff like, better for privacy, open source etc., those benefits came after.
