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?

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

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.

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

What is your favourite summer outfit? Why?

NickelBack.

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

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.

Trump is shot, tackled by SS agents, yet then stands, defiant, with fist high, and 52 hours later, walks into the Republican Convention to thunderous applause. Is there anything that can stop this man, who loves his country? Does he get your vote?

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.

BoB's answer to Is Stan from Eminem’s Guilty Conscience the same Stan from Stan?

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.

What measures do celebrities take to protect their images from being used for commercial purposes without permission? How much does this typically cost them?
