Is it fair to judge a person's ual orientation by the music they like?

music has nothing to do with being gay,no one has said stuff like that to me even though everyone knows i luv tokio hotel and i always wear tokio hotel badges,but seriously no one has ever asked me if i was gay based on that,even though i always metion how i`m crazy about bill kaulits whenever i`m talking to someone about music.she might use that phrase alot instead of emotional and mushy
