I think the western perspective is that bubbles are effeminate. Since there is a guy using bubbles, it is a male using a technique that westerners may expect a female use. I am from America and just stating things as I partially see them (I have trouble accepting bubbles myself, so maybe this is why). Living in Korea I think I can understand how an Asian might disagree with me on the use of bubbles.

I'm teaching English in South Korea currently and it is not uncommon to see two male students using the same chair while watching a movie or otherwise relaxing: someones one will sit in the others lap. Male students often travel to the bathroom in groups, just as females, and often fondle each other (small touches here and there). Yet they are not 'gay'. I have no problem with this of course: it is a different culture. I'm sure there are countries with even more 'macho' men, and the accompanying mindset, than America. The point is perhaps you have problems with bubbles because you are from a different culture. Maybe Japanese are like 'dude, I wish I could kill people with bubbles. That is so cool.'

Anyways you think we have it bad just watching someone get killed by bubbles? Imagine being the guy getting killed.
