First, this was never about your opinion. It was about an article that complained about music being used in advertising, songs being popular, and people being inspired by a band. That was the opinion you cited as a good reason to hate them.
Second, how often does that actually happen? Considering it’s an internet meme to shit on them, how often do people cite Nickelback as their main example of rock ahead of, say, Nirvana?
Third, why is it disgusting that people mention a band you dislike? Can you not simply correct them and suggest the bands you ACTUALLY like? Does it have to be “hate” rather than “I’m not a fan”?
Fourth, how the hell did Nickelback ruin rock? Is rock so fragile that the Eagles can’t be enjoyed because of “How you remind me” existing? There are bands far worse than Nickelback, but they aren’t successful so you don’t care. If Nickelback weren’t as successful, you wouldn’t care about them either.
