I actually had an example of Sam from next door, but scrubbed it as it would be immediately recognizable to anyone who knew me. Suffice it to say I know a Sam next door who is an extremely vulnerable person, with multiple vulnerabilities, who has had been trans presented to them as the ( ridiculously simplistic) explanation for all their many complex difficulties and now wants to be known by their chosen pronouns and has started on the pathway to go down the medical route.
There is no doubt in my mind that this will be utterly disastrous for this person and will compound their already many challenges. So no, I won’t use their preferred pronouns, as I do not want to play any part, no matter how small, in this young person’s train wreck journey due to this ideology. I see that as being utterly unethical.
And actually I don’t think trans people exist. Gender/ sex Dysphoria exists. And people with it need proper, informed healthcare. But even according to Stonewall, those people make up only a tiny part of the ( socially invented) category of ‘trans’.
And what you can there ‘extreme’ cases are happening all over the country, all over the world, every day, because of the social and cultural environment being created by people, politely and ‘harmlessly’ respecting pronouns.
