However, it does make it gross to that child. That's what a subjective opinion is. Subjective. That's pretty much the key word of that phrase.
Pretty sure the moonspeak artist isn't here to take criticism on a semi-bestiality wank comic, so I fail to see why we need to be thoughtful in our comments. And people are more than free to say whether they like something or not.
You're of the subjective opinion that someone saying they don't like something that you do like makes them a brat. I'm of the subjective opinion that it just means you have different tastes and you shouldn't let what a random anonymous internet user thinks about how you get your rocks off bother you.
