Yeah, that can be really stupid.
By saying that, you're basically saying that anybody who doesn't like your stuff couldn't POSSIBLY have a good reason for it. No, no, they're just stupid little "haters" who only don't like your stuff because they just don't like anything. Having been on the receiving end of this word in that context many times, I can tell you it's not in the least bit true.
If someone were to say that they hated my artwork, or my characters, I'd be "eh." That's their opinion, and they probably have a good reason for it. I'm not going to call them a "hater" and spend ages ranting about them and deluding myself that somehow I'm this amazing genius that NOBODY with any form of a rational mind can not like.
'Cause let me break something to you.
There's nobody that amazing. Someone is always going to dislike your work- and yes, maybe sometimes just because they don't like anything. But more often and not, they have a damn good reason for it. Think before you use the word in that context, folks. You'll sound a lot less stupid for it.
Also if you felt angry at me reading this journal, I suggest you pause and take a good, long look at WHY you're angry. <3
