A perfect non-anger example of how tumblr gets shit wrong is this post by a user called Yamino, of her golden satin mice. It says in the original post that they're her mice. Almost every new text added to the post is how they're definitely rats and how the people calling them mice are wrong because reasons.

She's reblogged the post multiple times to go 'they're mice. I know they're mice. They're my mice. I bred them' and if you look at it now, most of the text you'll see in the reblogs is about them being rats.
