Am I immoral for using a variable name that differs from its type only by case?

Question

What is the reasoning of those telling you this is bad? I do this all the time. It is the simplest, expressive way to name a single variable of a type. If you needed two Person objects then you could prefix person with meaningful adjectives like

fastPerson
slowPerson

otherwise just

person

is fine with me.

I use this pattern a lot in method signatures. If I'm unable to provide an alternate descriptive name then IMHO, there is nothing wrong with this.

What is wrong would be if you have two types Person and person then that is very very wrong.

I use it all the time for temporary object references. I would avoid it like the plague for primitive data types.

Person person = new Person(); // okay

int Int = 42; // pure evil

If someone says that is evil, ask them if this is better:

var abc = new Person();

If the Person is a general Person in the context, then "person" is a really good name. Of course if the Person has a specific role in the code then it's better to name her using the role.

I suppose I'll get downvoted for saying so, but ...

Having just come through a century witnessing epic murder and greed, we programmers are truly blessed if the most immoral thing we can do is name a variable.

I don't think it's necessarily "bad", but obviously if you can qualify it to give it more context, like what sort of person it is (you are dealing with only one of presumably many possible persons), then someone else picking it up may understand better.
