ThinEnd I find it helpful, whether writing emails/letters or speaking in real life, to stick to three points.
Sometimes I only mention one, depending on my audience and depending on what I think will get them wanting to know more.
When I went to see my new MP, I spoke about the following (and left him with some articles);
Speech (I mentioned Maya, Harry, and women being banned from social media).
Spaces (Sports, toilets, changing rooms, prisons, refuges, whatever is most important to you among those).
Safeguarding/Schools (I mentioned the Tavistock whistleblowers and the guidance given to schools about children being able to ‘identify ‘ into the spaces of the opposite sex, so also links into single sex spaces as above. If I had children in school I would be bringing in more specific topics on that).
I find if I think of those three strands, I can then find a specific issue for each one that I particularly want to highlight.
I call them ‘the three S’s’ and they really help me focus.
