On the other hand, I'm cisgender and would like to think that I can accept that fact without thinking it makes me some kind of victim (...of what? the existence of trans people?)

It's the same with any majority; if a white person thinks they're victimised by being referred to as white, then it's probably the white person's problem and nobody else's... sure, cisgender is a relatively newer term than most, but so is scientific acknowledgement that transgender people exist in the first place
