First we need to understand what 'privilege' is when specking in the context of minorities.
Let's start with the most obvious of privileges: Male Privilege.
Male Privilege is the direct effect of living in a patriarchal (male dominated) society. If we rewind time one century, we still see women in many countries fighting for what seems a basic and universal right - the right to vote. If we shift the time forwards to NOW and move our focus overseas, we see women who are not STILL allowed to vote and who are not allowed out in public without a male relative escort.
Shift our focus back to our wonderful Western nations and scratch the rosy surface away and we still find women woefully under-represented in positions of political and financial power. Go a little deeper and we find out that women have a one in four chance of being sexually assaulted by men. We also find that women are paid less in comparative jobs to men and female children are paid less attention in the class room.
I could go on and on, but instead I'll link you this list of
male privileges.
So now that we have a basic idea of what 'privilege' is.
Basically it's a set of rights and special treatments that belong to the privileged group which cannot be accessed by the oppressed/non-privileged group. To the privileged group (men) these privileges seen 'normal' - something that they have always had and always will have, so they don't seem like 'privileges' or 'special treatment'.
But to the people who
don't have these privileges and don't get this 'special treatment', they seem like pretty amazing things to have!
Or, in simpler terms, imagine we live on a cold, icy continent. By default, all men are given big warm windbreaker jackets lined with warm women's hair. Whereas the women are forced to have their heads shaved to make the jackets and are not given jackets of their own.
Not only is privilege something
extra that one group possesses over another, it's something that comes at the
expense of the oppressed group (i.e. men's institutionalised power comes from denying women power).
So how does cis privilege fit into this?
Well, the main perpetrators of trans oppression are cisgender people. Thankfully we're pretty bad at oppressing our own kind, so the sole source of oppression faced by trans people if from cis people.
For example, if I'm kicked out of my job after they find out I'm trans, it won't be a trans person making the decision, it will be a cis person. When I'm stabbed or bashed on the street, it won't be trans people doing it, it will be cis people. When I'm turned away from a nightclub because they don't want any 'trannies' confusing their male patrons, it won't be a trans bouncer denying me entry, it will be a cis bouncer.
So it's pretty safe to say that 99.9% of the oppression we face comes from cis people. Oppressors have a position of
privilege because their power allows them to
deny us basic things that cis people have, like being able to use the changing rooms or toilets in a department store, or gaining employment without being discriminated against. Cis privilege is
invisible to most cis people, because these things are NORMAL to them - things that they have never questioned their right to have - like the right to piss and poop in the toilet that fits your gender expressions, or the right to not be fired for wearing clothes appropriate to your gender identity.
Here's a
list of cis privileges that cis people take completely for granted, as they never have to fight for these things and have never been denied these things due to being trans.
And if your cis, you have these privileges whether you like them or not, just as men have male privilege whether they like it or not, white people have white privilege whether they like it or not, upper-class people have class privilege whether they like it or not, able-bodied people have able-bodied privilege whether they like it or not, etc, etc.
So if you're cis and speaking in a trans space, please,
remember that you speak from a position of privilege and try not to shout down the trans people when they are pointing out your oppressive behaviour.
Because when you do this
you are asserting your cis privilege and it is
oppressing trans people further.
