Why do people hate Nickelback so much? What makes them different from other popular bands like Linkin Park, Green Day, etc.? Is it just because they're Canadian or what?

Those opposed to the band are simply louder and more vocal than the true fans. A matter of opinions.

There will always be that one guy or gal. They may have friends also, so opinions spread, growing in strength , spreading yet further until the humble opinion of one becomes a near fact to many.

I doubt many hate them for being Canadian. I was going to say no one, but never say never , so to speak.

Am I the unique Gen Z if I dislike TikTok and prefer the 2000s technology trends like retro consoles, CRTs, and CD/DVDs?

NickelBack.

Anyway, why are they so despised in comparison to Green Day, Linkin Park, etc ?? To use an analogy, it is like comparing the smoking/stoner crowd in high school, the athletes and finally the unpopular souls.

Canadians are generally likeable people , so NickleBack are most likely ok guys.

How many of you have had your parental rights taken away because of lies and no truth whatsoever, and did you prove the lies that were told about you to be false either through drug testing or another way, but still had your rights taken?

NickleBack may appeal to many, but the majority rules as the saying goes and the overwhelming majority of more vocal proponents voice the opinion the music is bland, generic and commercial, not necessarily in any particular order.

Even I have cracked a few jokes about the band but I did so not intending any ill will or malice toward the band. Going with the flow at the moment I believe as NickleBack was the topic of the moment.

Which country do you recommend for me to live in, England, the USA, Italy, Spanish, or Austria?
