Do you have something against twins who look very alike?

In media and culture, when the stereotype of the "good twin" and "bad twin" isn't used, they almost always portray twins who are practically the same person. I always see complaints about this, which is true; saying that all twins are a certain way is harmful to everyone. But reading most comments, it seems like all twins are very different from each other. And when something appears depicting twins who have very similar tastes, or those cases of adult twins who dress alike, people always seem to judge. I know it's starting to get extreme, and often it can be a strong dependence between them, but sometimes it seems like an exaggeration to me. From this subreddit, it doesn't seem so, but are there twins who are really very similar beyond appearance? In tastes and interests, I imagine so, and why does this seem to be seen as something bad in all cases?
