So can I self identify as having paid my taxes ??

Here is an article from the NY Post talking about an NCAA swimmer who wants the rule changed prohibiting the likes of “Lia Thomas”, who is biologically male, from participating in women’s sports.

So if “Lia Thomas” can self identify as being female, and everyone on the progressive left agrees she is “female”, well then why the hell can’t I self identify as having paid all my taxes ???
