I'm a lurker... don't post often but read a fair bit and this thread kept me awake last night.
I'm a board level marketeer - One of the key frameworks is Segmentation and Targeting.
The key point of segmentation is to group consumers with a similar need to enable effective communication / relevant products and services / messages that resonate etc.
Frustration is created if you are in the wrong segment - we've all had crap sent that's of no interest because it is not relevant.
So WHY do trans women (particularly) want to be accepted in to a segment of the population which is not relevant to them?
Medical needs are not similar - Women cervical screening, maternity, menopause support and a whole host of others
Social Support - Post children back to work schemes (predominately women), pre / post natal support networks
Career Support - Fair Wage, Maternity, Keep in touch days etc.
Yes not all these apply to all women and they are hundreds of other examples but all women can see the benefit for their category because ... the need is the same which is primarily driven by biology. (Just be cause I can't have children so won't use maternity services doesn't mean I can't see the benefit of maternity services etc)
So WHY would a transwomen want to join a segment which does them such a disservice?
From a purely altruistic point of view it would be better for a trans category to be clear about the need that they want satisfying - to enable it to be effectively satisfied. I think many posters have identified within "transgender" there are conflicting needs - so this creates further issues! Wanting to be "women" is not a clear need / to what end and how does it benefit them - they will be ineffectually serviced if this is not clear.
This lack of a clear segmentation / similar needs makes it virtually impossible for organisations to target segments with the relevant service / products further creating frustration on both sides.
It's like a person with healthy tonsils demanding access to a tonsillectomy - why!!
