Hi Rana,
Yep - Alpha Males are a good thing.
Two reasons -
In Nature it is Normal for the most powerful, strongest male to rise to the top (i.e the Alpha Male), think of Gorillas, Wolfs, Lions, even Seals, Walruses. With this strength and power also comes the privledge of mating with the Females. Every Female animal want's to produce offspring with the highest chance of survival, strongest instincts, this come from mating with the Alpha Male.
In Human society, Males have a very hierachical structure, the fittest, cleaverest, strongest most able males will achieve success in business, sport etc. Men have to be competetive to suceed in life. Boy's are brought up to understand it is good to win, there has to be a leader and they play, experiment doing this. They need a STRONG ROLE MODEL. A strong male influence in their lives is essential to this. Typically the male role is the hunter gatherer.
Girls on the other hand by nature at not so competetive, achieving success by co-operation, communication and fulfilling the nurturer and emotional role, offering support and empathy.
So my opinion..... Alpha Males are required, if we wish the male species to remain with us (and I do!)
