The argument that faster is better has some limitations. Going faster does make your bike more stable and harder to push over. However, a gust of wind essentially initiates a turn, and the faster you are going the sooner you are off the road or in the other lane.
I'd like to support the observation that it is important to be aware of wind blockers like big trucks, hills, and buildings. Even large bridge supports can block the wind. The sudden absence of a strong wind you have been leaning into can send you off the road or across the center line.
Also be aware that a steady wind from one side does not mean there can not be a sudden gust from the other side.
