So I'm trying to begin to speak out about things I hear and see. At least within my Family since I know that it's the easiest place for me to start. Unfortunately, its not going to be easy. My mom is a teacher and has a very diverse group of kids from Islamic to Jewish to even a few other POC. So its no worries there but at home its a different story. My brother has some mental disabilities. He has an IQ of 64 which puts him at a borderline. Its complicated to explain over the internet exactly where he is on the scale but he's intelligent to the point where he understands social construct and how society works. Unfortunately he has gained some bad habits from The Sperm Donor. He has a tendency to say some racist things, listen to some very racist and sexist song paradies and the way he talks with The Sperm Donor over the phone isn't very nice. The Sperm Donor has never been a very good parental figure and he himself is a little racist, fairly homophobic and transphobic and just not very nice. Some of it has escalated with his marriage to The Step Monster (who likes to try and insert herself into my life but that's for another day) My mom has to work a lot and she's constantly creating her lesson plans so I don't think she always hears everything but I hear a lot of it. Today I finally said something. I heard him playing a song about sending some group of people back to where they same from (I couldn't hear the group but I know they werent a group of white people.) and my brother laughed. I told him to not laugh and that it was rude. He asked why and I said because it isn't nice to say those things and I don't want to hear it. I don't think he completely understand because he didn t change the song or anything but I don't want to assume. Does anyone have any advice on how I can try to fix this problem? It isnt just because I don't like it and it isn't right. My brother is on his way to beginning Independent Assisted Living which means that he'll move out with a roomate and have to take care of himself. And one of his best friends is POC and gay, whom I've also heard scold my brother on some of the things he says. Keep in mind that my brother does have quite a few mental disabilities and has been in a toxic environment from The Sperm Donors years of influence (I.E. jokes and conversations) not to mention some jokes and conversations he's had with my moms boyfriend (who is also a bit racist towards a few ethnicities.) He has autism, asbergers, anxiety and possibly tourettes as well (this hasnt been officially diagnosed because it could just be a lack of a filter (which might be the problem regardless but alas.)) I'm trying to come up with a plan to help him. My mom is stressed out so while I think I'll make her aware of it, I don't want her to stress about this as well. If anyone wants to reblog or send me a message with some advice or ideas, it would be greatly appreciated.
