Faulty Premise, Invalid Evidence
Why is it that the powerful masculine cards tend to be seen as bad?
Emperor- domineering and suppressing/controlling
Hierohpant- Oppressive Structure, blind dogma,
Magician- hell, ive heard him called a manipulative salesman before.
Oh, Zechariah! Tsk, tsk, tsk! You can't base a premise on mix and match like that if you're going to argue such a point. For example, the Magician--you may have heard him called a manipulative Salesman, but his definition in Waite is:
"...the divine motive in man, reflecting God, the will in the liberation of its union with that which is above. It is also the unity of individual being on all planes, and in a very high sense it is thought, in the fixation thereof."
Hardly anti-male! And what about the marvelously positive definitions for Hermit, Hanged Man and the male angel in Temperance? Even the very male Fool? And if you're picking and choosing, then why ignore definitions of the High Priestess being a bitch? The feminine moon being moody and deceptive, the Queen of Swords being a cold, depressed, divorced woman? Why not point out Eve there in the Lover's card, the one who listened to the snake and lost us Eden? And what about the Thoth deck where Strength, usually a very positive female card, has been re-named "Lust" and defined with references to the whore of Babylon?
You can't stack the deck with definitions you've hand-picked and then say, 'Sexist!" Because if you can do that, believe me, I can as well, and I can easily point out, with my hand-picked definitions, that almost all the male cards are overwhelmingly positive. And given that there are twice as many more male than female figures in the deck, even the ratio of unfavorable to favorable definitions for the males is about equal to those for the female.
I'm afraid your evidence of anti-male bias is unconvincing. If you want us to believe you, then you really need to be more scientific about this. Go through the definitions on several decks and prove that anti-male definitions are more common than pro-male or anti-female definitions even when the overwhelmingly male ratio of the cards is taken into account.
Otherwise, all you've proven here is that you, personally, are sensitive to the negative (reversed) anti-male definitions and notice them when you hear them--but you don't notice the positive definitions, nor have you bothered to take into account that you're at least twice as likely to hear about about a card with a male than a female. Hence, the appearance of a bias where there may be none.
