Our western societies are based on male dominance:
In almost all societies the wives would assume the station and position of her husband upon marriage:
any girl marrying a duke would become a duchess, there were (are?) no duchesses in their own right, but for example a dowager duchess who married a Mr. Smith would become Mrs Smith rather than him becoming a duke.
There are countless examples of this (See Norway>> Princess Ragnhild, Fru Lorentzen and Princess Astrid, Frau Ferner, the husbands were probably offered a courtesy title but only because this is royalty, not aristocracy)
PeDe in Austria until the fifties woman would even share in their husbands academic titles (Die Frau Doktor probably never even attended secondary school, only her own wedding - a female Doktor was called Die Doktorin)
So in any case I would assume Mary title would be the same as Maxima's and Letizia's:
Her Majesty, Queen Mary of Denmark
Mares won't be addressed as Queen, but Queen Consort, why she would be addressed differently?
Late Prince Henrik hold a grudge for being only Prince... Daisy isn't naive she knows the rotten creature lurking around, she won't admit her DIL to be addressed as Queen.
Sorry Mosh cry baby you won't be Queen!👎😘
