No, partially (humans affect climate, but climate changes naturally to a far greater degree), no.
There's no universal "one size fits all".
I think you have a very severe memory issue.
In all my life I did respond to you directly three times going by post search. This one, one time in a thread over two months ago (and did mention you another time there, but didn't respond to you) and twelve and a half months ago. Once I argued your use of the word antiquated, once discussed a button bloat topic.
On the other hand, what evidence shows the opposite?! Again, the very people that "don't fit society" still exist within it in some form. How then, tell me, does that apply to Blue Mage that have no access to Duty Finder at all?
That being said, again, Blue Mage cannot be used in Duty Finder, but it is possible to make it usable without actually changing anything outside of it.
That's the problem here. You are the one adding to the facts.
"Square peg in a round hole" is the idiom, right?! Where, do tell, does it say that it doesn't fit?! I see that it is IN the hole. It is a fundamental difference, because your 'doesn't fit' is at best implied, at worst just an overactive imagination. Or do you need me to bring in the definition of 'in' to you now?!
Well...the one that's giving it different meanings, of course. Language is ever-changing, but idioms are idioms for a reason. Idioms shouldn't change, otherwise they stop being idioms and become personal sayings at most. The part about fitting in does not exist in the idiom. The idiom only talks about the peg that's a different geometrical shape than a hole, being in it. Which means that it simply does not match it properly. There is nowhere in sight, neither in the idiom itself nor in its original meaning, anything implying that it's meant to mean that you cannot put a square peg in a round hole. At all.
