Popculture perpetuates icons of wizards who are elders or children.I don't think anyone looks at Elminister and thinks he looks feminine. A wizard's garb is based on the type of clothing worn by the wealthy or the scholarly in days gone by. We still wear such clothing at high school and college graduations and court rooms (in some countries). And of course the beard represents not just masculinity but also knowledge and power. So when you see a dude in a robe with a long flowing white beard you know he's wise and knowledgeable.
Relatively speaking, children and elders are more androgynous. Children havent fully developed sexually yet. Meanwhile, elderly males and females go thru hormonal changes that make them more androgynous, both behaviorly as well as physically similar to each other.
A dude in a longbeard signifies elderliness, and when accompanied by other symbols of femininity, becomes more overtly androgynous.
I am focusing on masculinity (an attractive virile jock) versus androgyny (whether youthfully pretty or agedly wizened). But consider the 3e icon Mialee, being a female who is likewise stereotypically androgynous for a wizard.
D&D tends to stereotype magic as a heterosexual union of masculine and feminine − an androgynous conflation. Compare Jung Mysterium Coniuntionis. The uncritical use of this trope can become a heterosexist sexism, that inadvertently stereotypes the androgynous gender.
I want to see goodlooking wizard jocks (and some of these gay masculine couples), and by extension, more gender diversity among wizards.
I also want to avoid tropes that exoticize an ethnic group, making them "magical" as a stereotype. (Compare how such a trope alienates and dehumanizes Roma, for example.) By extension, I want to see ethnic diversity as normal among magic tropes.
I want to see sexy white men who are wizards. Without attempts to distance or alienate this identity group. While within a context of normal human diversity among wizards.
Every kind of human is mysterious and magical.
