“Traditional” masculinity is not about the man or boy “suppressing” their emotions, but about controlling their emotions instead of letting emotions overflow and control them. It is about decision making that does not “suppress” emotions but is not made just because of emotions.
“Traditional” masculinity is not “naturally aggressive” indescriminately but is also not afraid of being aggressive when it is called for for good reason.
“Traditional” masculinity does not shy from competitiveness when competitiveness is called for. It recognizes when teamwork is called for, as well as when competing for your team is called for. It does not see teamwork and competitiveness as mutually exclusive. Contrary to modern politicized pop psychology.
“Traditional” masculinity is not about “dominance”, but it is also not about surrendering your own interests either. Knowing the difference between the two is not about “traditional” masculinity but about education and values. What is wrongly considered as “dominance” has sprung from how men and boys are taught to put “women and children” first, and taking the risks, putting themselves “at the front lines”, in the lead (in war or in work) securing that objective. Rather than being domineering or anti-female it is quite the opposite. That does not mean “traditional” masculinity is about suppressing women, but women must really decide when and how the roles they seek are really for their family unit or just for themselves, just as must men.
