If political views gives this bitter old lady an urge to hurt your child then she isn’t a safe person. My parents and I have different political views that we as adult have had many heated debates over it, however they have never ever decided to treat my son differently because of it. My husband’s family on the other hand, we don’t agree in a lot of things (especially political) and his grandma have made many comments to my husband in regards to my beliefs and behaviors and telling him to “put his foot down” and stop letting me decide what is best for MY child. We have decided they aren’t safe people for my son so they have very limited contact with him, and when they do see him they aren’t allowed to be alone with him. I do not ever see his family since they have been very hateful and racist towards me but I don’t stop my husband from seeing his family so I trust him to respect our agreement.
I know you have a history of opposing political views, but I don’t see how these particular instances has anything to do with political views so much as she is toxic in pushing her own personal beliefs. How she treats you is not indicative of any political party, just that she is toxic. I have very opposing views to the rest of my family (I’m liberal leaning, they are very conservative), but I would never let that play out and destroy our relationship. We just know not to talk about politics and change the subject if it gets brought up. I would put my foot down and limit contact with her due to her toxic behavior
Id completely disconnect with her and get your daughter a disney+ yourself. Someone like that can't be reasoned with and is not worth the effort. Family relationship or not, she's toxic.
My grandfather on my mom’s side starting cutting me and my younger brother out (I was 15/16 and he was like 9/10 at the time) simply because of political views. Which keep in my mind my younger brother was a small child yet and had no opinion on politics. Simply just decided since my parents and I don’t agree with his values and stance on political topics, we weren’t worthy of being his family. With that being said, no you are not the asshole for limiting contact when your children’s great grandma is being a c*nt about this. Sounds like she’s expecting it to happen if not encouraging it
