I suspect the proportion of transgendered people on WP might actually be less than in the general population. Those guys and gals probably get enough exposure to bullies in real life.
Online services like Wikipedia are, or at least appear, attractive to marginalized persons. The ability to conceal one's minority status means one will presumably not be harassed for it, and Wikipedia's bully culture gives them the opportunity to be the bully instead of the victim. Your rationale is also inconsistent with decades of studying of bullying, which has consistently indicated that a significant portion of adult bullies and abusers were the victims of bullying in childhood; having been bullied is at least somewhat predictive of becoming a bully in later life.
