Not correct.Bisexuality is being physically attracted to both mainly characteristics and female characteristics. There's another form of attraction, which is being attracted to the person, to the individual and the feelings he/she makes you feel, in spite of what gender this person is. It's like the difference between claiming to accept both black and white people or to just ignore the skin color in favour of personality, skill, intelligence and so on.
Wait...I always thought physical attraction had nothing to do with emotional attraction. They're two separate things...people should fall in love because they find someone physically attractive. Shouldn't they? So you're defining sexuality, by who you are physically attracted to?
What about chronic drunk brainless dude proud of their ignorance and with a need to attack those who know something?
