You're not really having a moral dilemma about what other people think about a single attraction preference, are you?
The list of attraction preferences is hugely long. This is one thing.
Of the billion of things to occupy worry, concern, & mental run-time this bothers you?
Anybody that spends a microsecond concerned with one of your attraction needs more than a life, they need serious therapy.
You are a big boy, what you like is right, regardless of anything. It's yours - everyone else can take a flying leap, they don't deserve an answer and you're too important to worry about this. Own it and move on.
Besides...

Hypothesis was presented by Canadian anthropologist Peter Frost, who claims blond hair evolved very quickly in a specific area at the end of the last ice age by means of sexual selection.[27] According to Frost, the appearance of blond hair and blue eyes in some northern European women made them stand out from their rivals at a time of fierce competition for scarce males.[28]
That sorta implies you're
not alone in the preference there. =)
