At risk of re-activating an old argument discussion, I cannot help thinking that diversity will happen if the existing climate encourages it (or more realistically, does not actively discourage it). As one of the few reasonably vocal male grandparents on here, I notice how often posts make an assumption that the entire population of GN is female, and I wonder how many other other posts make assumptions that the entire population of GN is White Anglo-Saxon Protestant?
The key point is that I notice the male/female thing because it affects me, I feel excluded by it, and I am not afraid to lift my head above the parapet periodically and make a noise about it. How many other male users lurk here, read one or two (or twenty) discouraging posts, then leave with their opinions unheard? And that prompts me to ask how many posts also unintentionally similarly exclude those who are not cast in the White Anglo-Saxon Protestant mold?
We need to practice diversity and not simply pay lip-service to it, and we need to reflect that in the language that we use both in serious and light-hearted posts. On the very light-hearted "Ask A Question" thread, a recent poster asked "How many bras do you own?" while another asked "Were you ever a bridesmaid/pageboy?" showing that diverse thinking doesn't require a huge amount of effort.
Although I was never in a front-line position, like all civil servants of my era I underwent compulsory diversity training (diversity being one of the buzzwords of the decade), and the most valuable advice I took from that is that diverse-thinking is easy when you are facing your target audience - but much more difficult when you are writing. So before you post that letter or send that email (or post to a board like this), picture yourself stood on a stage addressing a crowd and read through what you are about to commit to while asking yourself if it would make sense to everyone irrespective of race, colour, creed, gender or sexual orientation.
Which is what I have just done with this.
