Disagreement about toddler

I'm very conflicted because my husband and I have a toddler son and another son on the way. Our son is loving ans caring and he does cry and is good on picking up on emotions. He loves to play with cars and jump, kick balls and be rough. He likes to play with cooking toys and stuffed animals. And this morning he asked for a hugs. He asks for a lot of hugs and is mostly attached to me. And his dad says. Go do push-ups as a joke and I said oh my goodness and laughed. I said he's 3. Then he started talking about there needs to be a balance. A balance of teaching him how to be a man. Then he started saying how my new school way of thinking is dumb and looked at all the years the old school way of thinking have worked. Yeah, like his dad making him feel like he isn't good enough because he was sensitive and wasn't good at a a certain sport ? I'm not shaming the old school way. I just want to try a different way. I don't want my son to feel ashamed to cry or hug. If he doesn't feel like playing sport, being rough or being the definition of what a man should be at the age of 3. I honestly don't know why he gets in these moods. Then he goes and tells me his way is the right way and my way is wrong. He couldn't even explain what balance meant to him when I asked ok what is balance to you when he asks for a hug? I want my son to grow up and be a love and respectful human being. If he's more sensitive. But again.... he's 3! It seriously scares me when he gets older because I don't know what will happen. I've never really seen this side of him and jts concerning.
