Well, as soon as you posit an underlying "reality" to trans identity which is more than the observed fact that some people believe themselves to be innately aligned with what they believe the opposite sex experiences in ways that others of their sex are not, you are moving from shared reality into ideology.
But really I just want to clarify what you mean by "inclusive , dignified and safe for trans people"
Do you mean in that society needs to accept and allow trans people to be trans people - people of one sex who believe themselves to align better with the other? And to ensure they are not insulted or threatened or made to look foolish? While their belief system is obviously offensive in that it projects the trans person's idea of reality onto others, it is no more offensive than many religions and certainly not something that should stop trans people partipating in society safeky and with dignity as long as they can accept others may not align with their belief system.
Or do you mean that society needs to accomodate trans people as being in a meaningful way actually the opposite sex, to the degree that they should have a right to the protections, rights and language of the sex they in fact are not, the right to impose their personal projection about what "fits" onto everyone else and force them into identities they may not find authentic, to redefine everyone else in society and law, to remove in particular women's right to say no to any male because he is male, to remove even the language to speak of a purely female experience?
Because if that is what you mean, if you believe the only way trans people get inclusivity, dignity and safety is if they are allowed to reshape everyone else's inclusion, dignity and safety to fit their own beliefs, beliefs many people find not just wrong but actively sexist and regressive, I have a problem with your ideology and I utterly reject it being described as "inclusion, dignity and safety" when what it really is is dominance, denial and repression.
Let us be very clear, the moment you accept just one person as being meaningfully a man or a woman despite being of the opposite sex, you have just told every single human being on the planet that their identity as a man or a woman has changed to accomodate a mental quality of gender regardless of how those people may feel or see themselves.
And that is not inclusive or dignified, and in the case of women in particular, potentially unsafe.
