Well, some people might need to rethink.
How would Boudicca have raised and lead a force of up to 230,000 (by Roman historians' counting) without having huge status as a leader, and without those fighters being willing to follow a woman?
Tacitus, the Roman historian said that the
Britons made no distinction of sex in their leaders, and he was the son-in-law of Agricola, governor of Britain who arrived on the island less than 20 years after the end of Boudicca's revolt.
Also, the Romans had no problem shoring up Cartimandua, leader of the Brigantes, purely for political reasons of course.
