You don't need an 'inclusive' definition. The reality is straightforward: a woman is an adult human female. As you already stated.
By contrast, a transwoman is a man who desires to be a woman, and perhaps also believes he is a woman, somehow. But he's not really a woman, and never can be, no matter how much he insists he is. Being male precludes this.
At most, he'll be a feminine man; a man performing femininity. Trying to mangle the definition of woman to include these men is ultimately fruitless, as it will be a lie.
Not all on the left share that belief, there's plenty of us gender critical leftists around, who still understand the material reality of who are the women and who are the men.
It boggles my mind how this has become the cause célèbre amongst certain other factions of the left in recent years. Particularly given how it relies on misogynistic stereotypes and is effectively erasing homosexuality.
