I think this song is more about the emotional trauma of having an abortion, than taking a black-and-white political stance on the topic....and you all are really kidding yourselves if you somehow think Xiu Xiu are sympathetic to the policies of the religious right
"A young friend of mine had gone through a long period of cutting herself, which we discussed over the course of two years. She eventually mailed me a knife she used which sits on my recording desk. Not long after this she became pregnant and came to know that she was not able to be, at this time, the kind of mother she knew a child deserved. She decided to, after deep and fraught consideration, abort the baby. She did this out of love. She named the zygote “Little Jizzo.” The lyrics come out of admiration for her, the crushing mix of sadness and correct relief that abortion can create. And out of white dwarf hot anger towards the U.S. right wing. As the topic elicits such crazed violence in conservatives, the only response seems to be to meet it with as much unhinged rage".
I’m at least 90% sure that Jamie isn’t taking a stance on whether or not he’s actually pro-abortion it’s just based off of the intense emotions that come with it
