The definition of attraction: the action or power of drawing forth a response; an attractive quality; something that attracts or is intended to attract people by appealing to their desires and tastes.

It is about desires and tastes, you choose to desire people of the same sex. A person may desire same sex people, Asian looking people, Black skin complexion, blonde hair, big breasts, small waists, tall or short stature, long or short hair, women that look like men, men who are girlish.

All of these desires and tastes are recognized as choice, except when gays add the same sex to attraction, so other than for political propaganda how come only gays claim an innate attraction.
