It's easier to add a disclaimer “Not confirming to gender stereotypes is not the same as being trans.”, but it's meaningless if the rest of the material is firmly embedded in stereotypes.
"I know about 8 trans people personally because I hang out and work in trans-welcoming spaces."
I suspect many people on this board know a similar number or more (how many people can you really know?) because they have trans children.
'Trans widows' - women whose husbands have claimed a trans identity late in life - might know less, because they don't tend to be so associated with queer community. However, I am sure they have a more in depth knowledge of the issues being discussed.
The gaps in your knowledge surrounding the Tavistock, and your lack of understanding of the wider issues suggest you haven't been thinking about this issue for very long. Again, I think if you really cared about trans people, you would be a bit more willing to acknowledge the flaws in gender ideology and harms that have been done.
