I'm taking a somewhat oppositional position to OP! I'm not gatekeeping anything, just expanding on the topic. And no, I personally have never collected anything nor do I particularly care for decoration, and I find being attached to material possessions to that extent says something not necessarily dangerous or immoral about you, but it does still. So, while being obsessed with toys is not at the core of any ideological or personality-dependent negative attribute (nor does it constitute one by itself), it does serve as a litmus test for whether the person is, you know, 'regular'. Come on, you go to a guy's house and he has nothing but Goku and Vegeta inflatable dolls and refuses to take off the Piccolo doorag in his 30s and you're not gonna think he might be a tad infantile and focused on less than important things?
