Hmmmm's Things

Personally I hate it. In a black and white manga it throws off the reading way too much. It's distracting, overall migraine causing, and straight up the worst censorship I've seen. Lightsabers are the better choice by far. Even the bars would work. But to scribble the entire thing in rainbow makes no sense. I wish it would stop because they ruin perfectly good manga. What is your opinion? Please debate with me why these are used and why you agree with it or disagree because it makes no sense.
