The Linux Foundation's report on diversity, equity, and inclusionin open source

It's not very long. Don't dive straight for the Conclusion because unlike in a scientific paper it is a finale and not a summary.

A simple first step to encourage an inclusive approach for yourself is to avoid using skin colour when describing someone. It is quite a tricky habit to get out of. As a useful side effect you get in the unconscious habit of noticing more details about people but it does take some effort to start with and takes years to become close to unconscious, depending on quite a few factors.

You might make a pact with your partner, family, friends or a group of colleagues and agree to call each other out. You might pick other attributes instead or add others. Do use common sense, though. Sometimes skin colour might be a useful attribute to use in a description but it should not be a primary discriminator that is reached for routinely.

I'm well aware that there is an awful lot more to an inclusive first mindset but it's a very positive and easily understood start that anyone can make without tying themselves up in knots.

Among respondents that feel unwelcome, twice as many have disabilities compared to all respondents.
16% of unwelcome respondents were transgender, compared to 4% of all respondents.

This suggests the sort of attitudes that make people feel unwelcome doesn't affect every minority equally, which was not obvious to me.
From the above, there may exist some specific behaviors that the community might want to focus on first.

But anyways, we got to know you as a person first, and that makes all the difference.

Cheers,

I do not think you realize how insightful is your own comment...

Come on now, we know that there's hardly anything wrong with writing Perl.
