But I feel that’s why people hate it, it’s too clever. Seems to get derided the same way a nerd kid gets beat the fuck up in school.
A tourist walking around with their phone in a selfie stick has put preparation and forethought into the endeavor. Before leaving their hotel to see some wonder of the world, they consciously thought, "I'm going to take a bunch of selfies today so I can post them on social media and gain influence because I'm somebody." This attitude represents everything many people blame for giving rise to the modern overcrowded tourist destination experience.
I'm sure there exceptions, and some people just like pictures with themselves in them, but this is the impression it gives off. You asked why people hate selfie sticks, and this is a likely reason.
There is a huge leap from being prepared to take a slefie at a famous place to this mentality, posting it anywhere on social media, and especially gaining influence or being somebody.
As an old git (45) it seems strange to me that today's youth have known nothing else but a world where sharing pictures of yourself on social media is the norm. It's like its part of the reason for living.
That said, it can be taken to an extreme. Photos of yourself should always try to be as candid as possible, and you shouldn’t be the main subject every time.
It absolutely bothers people around. If you're in a crowded place, selfie sticks are awful.
