Does talking about the same topic to others make me autistic?

I am already diagnosed with APD and mild ADHD. I was told I do not have autism. I really do not fit into an of the autistic symptoms except regarding special interests. For example I love Nintendo, Disney, and the general entertainment industry. Whenever I able to bring these topics up at an appropriate time I will. For example, I when I become friends with someone I will intensely talk about Disney to them but, after that I stop as it gets repetitive. Some of my friends though that are interested in Disney or Nintendo though we will talk about this stuff all the time. These are defiantly strong passions of mine but, the reason I do not think these would be considered special interests though is because they do not take over my life. If someone is not interested in my topics at all after I ask I wont bring it up to them. I also my interest arent a necessity to me, they are just something that make me extremely happy and I am quite knowledgable about. What do you think, does this sound like it could be a link to me having autism.
