Why is the question, "is your favorite time of year the cold frigid winter or the warm radiant summer? " biased? rewrite the question so it is not biased. *

The question is biased, and it is biased towards the "cold frigid winter".
Generally, people prefer comfort over unpleasantry and the cold is often one of the most unpleasant things related to over the seasons. People bask in the warmth of the sun's rays and it is comfortable since human physiology naturally desires the sun anyways.

The cold is typically what brings about a sense of death to living creatures and human's die from Hypothermia, Severe Frostbite, and several other symptoms usually involved with the cold temperatures producing a natural dislike and sense of fear towards the colder times of the year.

"Is your favorite time of the year the festive wintertime, filled with joy and hot chocolate or the comforting warmth of summer and swimming in a lake or pool?"
