This is horrifying. I'm so sorry. My parents were in a cult for the first seven years of my life, and among the many awful things, I wasn't allowed my favourite toys for the most ridiculous of reasons. So yes, I know exactly what this is like.
The person leading the cult had been doing all the usual things - stealing money, demanding sex from various women in the cult, etc, etc. The toy thing? He wouldn't allow anyone to give presents to their children unless they'd been purchased from his sport shop. So I had plenty of bats, balls, and whatnot, but not the toys I really wanted.
Anyway, I'll spare you the rest of this huge subject. Glad your mother recanted. My parents also did a lot of making amends after the cult collapsed (though alas, some of the toys I wanted had since been discontinued).
