You’re attempting to redefine the gender characteristic “man” in terms of physical sex characteristics “male”, which isn’t valid; this invalidity is proven by the existence of both intersex men and intersex women.
You’re also using the invalid term “biological sex” to refer to “sex at birth”, which can be male, female, or intersex — but due to your imprecise phrasing, your use could also refer to “current sex”, which is a modifiable state that can be altered surgically and thus invalidates your point further.
Minor49er, I don’t think you’re participating in good faith here. You’ve presented a view that doesn’t stand up to the facts after repeatedly being confronted with them in multiple threads, your concluding question “Don’t you agree?” is a direct quote from the sealioning comic, and you’ve asked the mods to delete this post in a different thread while continuing to engage here. You’ll need to shop your anti-trans trolling elsewhere, as it’s not productive for me to engage with you further.
