[PATCH] am: counteract gender bias

[PATCH] am: counteract gender bias

[Johannes Schindelin]

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), i.e. for
almost 11 years already, we demonstrated our disrespect to the pioneers
of software development like Ada Lovelace, Grace Hopper and Margaret
Hamilton, by pretending that each and every software developer is male
("his_tree"). It appears almost as if we weren't fully aware that the
first professional software developers were all female.

We know our field to have this unfortunate gender bias that has nothing
to do with qualification or biological reasons, and we are very sad
about the current gender imbalance of the Git developer community.

Let's start changing that by using the variable name "her_tree" for an
equal number of years out of fairness, and change to the gender neutral
"their_tree" after that.

You make it sound like the decision to use "his" was conscious and on
purpose. I doubt that was the case, especially 11 years ago, when these
issues weren't as publicized. Let's not attribute to malice on part of
the people who wrote those lines what can be attributed to linguistics.

Also, in all (?) other places we use "ours" and "theirs"; it looks like
git-am was a strange exception with "ours" and "his" (also, it was/is
inconsistent in using plural vs singular form).  Though perhaps it was
created before the terminology solidified...

As to why it was not noticed and not fixed: probably no-one worked
in this area, thus nobody noticed this (callee just don't care how the
parameter is named).

Instead of nebulous "fairness" (i.e., be unfair in other direction),
in my opinion it would be better to simply fix the issue, be consistent
and use common terminology.

I also thought that "ours" vs "his" was strange mixture of plural
and singular when I first saw it, but it turns out there was no
mixture.

It originates at 47f0b6d5 (Fall back to three-way merge when
applying a patch., 2005-10-06), where the code used $his_tree and
$orig_tree, (there was no reference to "our" tree), both singular.
They were copied to "git am" introduced at d1c5f2a4 (Add git-am,
applymbox replacement., 2005-10-07) almost verbatim.

The use of "ours" & "theirs" is now established, and I agree with
you that the use of "his" that is contained to the fall_back_3way
helper function (cf. contrib/examples/git-am.sh) is an oddball.

We should just use "theirs" to be consistent from the beginning, as
you suggested.  There is no need to churn the codebase for political
correctness to first use "hers" that everybody knows will *not* be
the final form.

I will change the patch to say "theirs" (BTW "they" is nowadays considered
not necessarily plural only, but can be used as a gender-neutral singular:
https://en.wikipedia.org/wiki/They).

However.

I strongly disagree that this is the correct course of action. In my view,
this has nothing to do with political correctness. It has all to do with
respect instead. And I find it disrespectful to quietly paper over the
issue instead of making a bold statement (which my patch constitutes).

There seems to be no support for my position.

Therefore, with sadness, I set this aside as yet another concession to
those men who are really comfortable to equate "programmer" with "he" in
their minds and at the same time feel utterly offended when addressed as
"How are you ladies doing today?".

I absolutely despise having to change this patch, yet I do not currently
have the time nor the nerve to insist on my version of the patch.

Johannes

P.S.: Having said that, I do notice that the communication on this mailing
list has become much more civil in the past few years. I am pleased by
that, and I am hoping for much more, to the point where we are truly
inclusive. It will be more productive, and also much more fun.

It was not my intention to imply that the original decision was conscious.

What with me being a non-native speaker, would you kindly suggest a commit
message that conveys the intention better?

[PATCH v2] am: counteract gender bias

[Johannes Schindelin]

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), i.e. for
almost 11 years already, we used a male form to describe "the other
tree".

While most likely unintended, this gave the erroneous impression as if
the Git developers thought of users as male, and were unaware of the
important role in software development played by female actors such as
Ada Lovelace, Grace Hopper and Margaret Hamilton. In fact, the first
professional software developers were all female.

Let's change those unfortunate references to the gender neutral "their
tree".

In my opinion more important reason than being "gender neutral" is that
Git uses the "ours" / "theirs" terminology in all other places - this patch
makes Git consistent and code easier to understand (it also removes
weird plural "ours_tree" vs singular "his_tree" in code arguments).

But nevermind that...

This actually is older than that commit by 9 commits.  I may have
said it already, but it originates at 47f0b6d5 (Fall back to
three-way merge when applying a patch., 2005-10-06).

I'd add this at the end.

	Doing so would also make the fallback_merge_recursive(),
	which is an oddball, more in line with the other parts of
	the system where we contrast what we have vs what we obtain
	from others with "ours" vs "theirs".  This inconsistency was
	also unintended.

I do not think changing these references to "her" and keep them like
so for 11 years is a proper way to show "respect" anyway, by the
way, so this round is a definite improvement over that version.

Thanks.
