The number of TIMs calling themselves women, I think this is actually not just delusion etc. but usage of an old psychological trick...
If we hear something repeated enough, and we don't have evidence to the contrary, our brain accepts it as true. Governments, advertisers, whoever, frequently use this to get people to think certain things, especially when there actually isn't any evidence to support them - typically short, 3-word phrases like 'safe and effective', 'illegal and unprovoked', 'transwomen are women'.
At the start of all this, a lot of people thought transwomen were TIFs. Now that more people understand that they're actually TIMs, they're swapping TWAW for 'we are women', and hoping that sticks instead.
Modern propaganda and advertising originated with Edward Bernays, and the trans brigade are employing all his tricks.
