The two are massively popular, with millions of fans. They're both known da many people. Just go up to someone and talk to them about either one and they'll say, "Oh yeah I know that."
People compare the two because, again, they are both popolare to the crowd.
To me, there are very few points that te can argue about the two. Fiction, mythology, can't think of anything else which proves my point that the two have very few things in common.
P.S. Please use correct grammar, it's best to do that to have people take te più seriously. Plus it's a very short domanda it should not be hard to revise it and correct it. Unless te a foreigner that is new to the English language.
The same reason we argue about fanfiction ships aka people we think should be together but are not together examples-Draco/Ginny, Draco/Hermione <3, Hermione/Harry, etc. etc. we like the challenge and we like to dibattito who is better. It gives people a sense of power, like they are going to win if they bring the other team down with insults. My preferito is Twilight sucks. Get it He is a vampire and he sucks blood. haha. THe unfortuanate thing about Twilight though is they have to worry about HArry POtter AND Team Edward and Team Jacob. sigh ow why that started idk because team edward has already won.
People like Harry Potter, and people also like Twilight. Many people are obsessed with one of the series, and think the one they like is better than the other. Plus, it is also fun to argue about it. :)
I honestly think it is just to get the proper Idea of fan preferinces. Sometimes I don't get the point. te can't compare Twilight to HArryPotter. They are 2 different novels with no bonds o connections between them. The only bond is that in a Harry Potter and the Goblet of fire, Cedric Diggory was played da Robert Pattinson in which we all know is now Edward Cullen. this spot is made to criticize twilight mainly. It is dominated da HP fan who possibly created the spot. And just want to express they're ideas and opinions. I find it undisturbing to express your own opinion(As long as it doesn't go to further and that's when Its geting annoying) Sometimes we tend to protect the 'thing' we like and prefer from all the obstacles.
