Masculinity are a set of traits socially attributed to males: strength, courage, leadership...etc. Women can have these traits too. Toxic masculinity is when these traits, which are good, get corrupted into something bad. Strength, courage and leadership become aggression, temerity and domination respectively. Masculinity doesn't need to be improved, human nature could use an upgrade though ;)

Stop giving too much credence to the pundits and be yourself. Men can have feminine traits and it doesn't make them less of a man. A man can be nurturing, sensitive and empathetic. Most men worthy of admiration have feminine traits. Lose the 'real man' trope. It does not promote anything healthy. Follow your conscience and listen to feedback.
