::2. It's a proven fact that heat always goes from warm to cold, and not the other way around; to do the opposite, to get cold to flow to warm, requires an energy source, i.e. the sun reheating that side of the earth when night turns to day. Entropy will never ever decrease unless that energy source happens. The same thing happens in a refrigerator; you can use the heat generated by the machinery inside it to send that cold air throughout it, ''but you gotta plug the thing into a wall socket to give it some power first!''

Note that entropy is a quantity like distance not a process.
I am going to go through your points in a table, stating which points I agree/disagree with and why.
First Point:
{| class="wikitable"
|-
!Sentence
!Agree/Disagree
!Explanation
|-
|You stated above "I am arguing that the second law does not apply to open systems."
|Agree
|
|-
|You claimed above that the earth is an open system
|Agree
|
|-
|The earth gets its energy from one source: the sun
|Agree
|
|-
|Turn the earth away from the sun, and what happens? It's called entropy, something you are denying is happening in an open system.
|Disagree
|At the bottom of my comment from earlier I say "I am '''not''' denying that entropy can increase in an open system. If you look at my maths, you can see that if we heated the coffee instead of allowing to to cool its entropy would '''increase'''."

Second Point:
{| class="wikitable"
|-
!Sentence
!Agree/Disagree
!Explanation
|-
|It's a proven fact that heat always goes from warm to cold, and not the other way around; to do the opposite, to get cold to flow to warm, requires an energy source, i.e. the sun reheating that side of the earth when night turns to day.
|Agree
|
|-
|Entropy will never ever decrease unless that energy source happens.
|Disagree
|My example shows an object radiating heat and its temperature and entropy decreasing. Heat flows out of the object and the surroundings do no work on the object so there is no "energy source" as you have described.
|-
|The same thing happens in a refrigerator; you can use the heat generated by the machinery inside it to send that cold air throughout it, but you gotta plug the thing into a wall socket to give it some power first!
|Agree
|What you are saying actually agrees with me. Consider putting a glass of water (this is our '''open''' system) into the fridge. It cools down and its entropy decreases. Same as my example above.
