Women find power attractive, and your confidence is a huge indicator of power. Toxic/objectifying men tend to have more confidence hence why they have more success.
You can be confident without being toxic but it really doesn't matter. If she's super into you, your objectification of her takes a far back seat and is only really a factor if she intends on marrying you.
Also this article just conveniently leaves out the importance of height and physical attractiveness. Typical for a woman to leave that out. Anyway... People who have an easy time dating also happen to be taller and physically attractive... coincidence? No.
One influences the other. You have more success if you're attractive. More success makes you more confident, which makes you more attractive.
