That doesn't follow. I could be incredibly sentimental about something and still very happily part with it for millions of dollars. You are inventing a dichotomy that doesn't exist.

Further, saying that men shouldn't have emotions, or display the same emotions, lest they be labeled "drama queens", is absolutely gross behaviour. It's one of the contributors to the male loneliness / suicide epidemic, and you really should do better.

Having irrational and excessive emotions and the associated negative feelings is the primary cause of extreme actions. You can do better at knowing things.
