Which one would you prefer?

Which one here would you prefer? Or, which side do you think is “ fair” is standing at?
The person who focuses on the person instead of the issue, or the person who focuses on the issue instead of the person? *(Alternative: "The person who focuses on person rather than issue, or the person who focuses on issue rather than person? - This is a more native sounding sentence with "the" omitted)*
First one has a heavy sentiment, and passion towards someone close to him( or her). *(If someone is "closeD" to someone, it means they do not easily open up to them. Like the slang I told you: "Keeping to themselves". So "close" is right, here)*
Second one, I think, is more like the so-called "fair" personality, treating everyone around him (or her) as the very identical person. *(Not wrong! But not necessary to write those~)*
So, it sounds each one has his (or her) advantages. *(yet again... you weren't wrong. But your sentence is a very familiar and informal style there. When you omit words like that, you are usually talking to a close friend :). Although it is more common for people to write like this now!)*
Ok, it is time to clarify my point.
I prefer the first one, who focuses on person instead of issue. Also, that is where I think “fair” stands at. The reason is simple: there is no such thing as what we are always talking about, the "fair". I think, we all (bad habit I admit, I always think of everyone in my own way.) treat everyone surrounding us in a different way! We all ( again…) do things in our idea of the relative "fair" way. 

For instance, simple idea. If we were colleagues, I mean only colleagues, not close friends, I would do what my boss asks me first. Afterwards yours (Here, I refer to those private things, to say nothing of businesses). Or just as well skip yours~ no offence, but it is general knowledge! That has nothing to do with being fair, and you can only say that I am good at flattering. Because of what? Why did I do my boss's requests first, or treat you in such a different way? Because you are not him (or her), right? That is why. I don’t think I am in accord with being allegedly “ fair”,  but I just did what I can do best. *(Totally impressed here!)*

For example another instance, still simple. What would you think of me, if I treated you, who I grew up with and help me a lot, the same way I treat my common colleagues? (I can picture the scene that you are disappointed!) Fortunately, that will never ever happen, as long as we are friends. Regardless of what you have done, I will help you in any case (Actually, I want to add “in my power limit”, but it sounds more serious without it, and I mean it as well!), but not look down on you with folded arms. On the contrary, if you are not, you expect me to do nothing and I don’t have to, right? Does it make sense? Or I am ruthless enough to see a doctor?...

Therefore, it would not be fair, if I did the same thing in front of two different men (or women). I would feel shamed and guilty to do that.

CONTINUING... So, that is why I like the first one, and I am trying to be fair too, but not the so- called definition. In sum, focusing on person rather than issue might be your friend or your enemy. He (or she) is worthier building a relationship with. As your friend, I will focus on you instead of matter; as an uncredited passerby, I will be focused on matter rather than you. Give me your comment on it, I just get bored and try to make something out of my dirty identity! XD. And…. the most important thing is the correction lol. Thanks always!!!

Leroy~! Look how few corrections I made! And most are really only native suggestions. Ask me if you have any questions, though!

In reply to your post... I really agree with what you say. I think it is important to treat everyone as individuals. But sometimes it is obviously important to go against those rules - like following your boss's orders before your friend's. Even though none of us want to follow our boss's orders sometimes, haha!
