It appears that you're defining masculinity in and of itself as toxic. Masculine and feminine function as yin and yang, as dualistic complements. The masculine is simply structure, force, or closure. The feminine is flow, softness, and openness. Each human moves with a balance of both.

What's toxic is when the masculine is out of balance with the feminine. When structure, force, and closure crowd things out because there is not enough flow, softness, and openness. Simply making a decision and acting on it is not in and of itself toxic. It's the inability to adjust later that is toxic.
