user1458: So Why do people tend to think anime is weird porno? got closed as opinion based. 
Personally I don't consider this to be opinion based, as the question states

Is there a specific reason as to why this stereotyping came to be?

Which as far as I believe could be backed up by facts. The comment by Toshinou also seems to hint to this.
So, why is it considered opinion based?

user1458: Seems that most close votes were coming based on the title of the question, and the lower quality question I linked within it. And not specifically for it being opinion based.
