And "white people" are not the "men" of race. Now I think it's pretty clear what the catalyst of this post is but it is far from the only time I have been tempted to write about this. No MP, not that this would be. And this is my first ride on the drama llama so please be gentle.
As a WOC, I deal with racism and sexism pretty much daily, so I feel qualified to talk about issues. But as a straight, cis person, I don't feel qualified to extend this topic to LGBTQ issues, though those who have that sort of experience and welcomed/encouraged to give their input in that manner.
Drawing parallels between oppression can be a very useful tool in explain 101 social justice concepts to each others. I am not saying that telling someone "think of it like men/white people/straight people" is never appropriate to use. I am saying there is a point where the situations stop being analogous and you might want to think a bit before using such parallels. The reason is these oppressions can and do function very differently, and beyond they basic level they require more nuance in their discussion than saying "it's like white people/men."
Now to me, the obvious difference is that sexism polices men and masculinity while racism does not police white people, or if it does it's in a very limited way (e.g.- you should not associate with "those people" type of things). I am not saying that racism is worse than sexism, I am saying they function differently (you could make the argument that an oppressive force that oppresses its own members demonstrates just how bad it is). I am also not saying that men experience gender policing to the extent women do, that should be obvious.
Now there are clearly some similarities, both institutions are enforced by the oppressive group, even if the oppressive group is oppressing its own members. But I don't think this is a blank check to write off other people's concerns. I am not saying do not ever use these parallels, I am saying think about it when you do, especially if you are using it to dismiss someone's concern. And especially think about it if you are a member of only one of the oppressed groups you are drawing a parallel to. If you are a white woman or a non-white man, do you really have the knowledge to say "this is like racism" or "this is like sexism"? You might, but really think about it first.
