My dad said my husband disrespected him

My husband and my dad have a hard time getting along. My dad is very old school and has old school opinions. He just grew up in a different time. Me and my husband have 3 kids together and I have two bonus kids. Our kids together are 7 months, 4 and 8. My bonus kids are 15 and 18. My bonus son is 15. Bonus daughter is 18. We were over my parents house and our kids were rough housing. My 8 year old was hitting my bonus son with a pillow. My bonus son has these piercings on his cheek and I'm not really sure how it happened but when my daughter hit him in the face with the pillow (tmi for blood) the pillow caught his piercing and pulled it through his cheek. So we just heard a scream and my husband was looking at his face. One of the balls on his piercing was stuck in his cheek and he was trying not to cry so my husband took him in the bathroom and I was trying to help. My husband was just trying to get the ball out of his cheek and he started crying. He finally got it out and put a bandaid on his face for him then hugged him because he was crying and my dad said something along the lines of "Men are becoming weaker and weaker these days." And started talking about how when he was in the military he has seen soldiers cut off their own fingers and not cry. My daughter was also crying and trying to apologize to her step brother and my dad was like "Don't apologize. He needs to grow up." And then my husband told my dad to STFU and my dad told my husband he better respect him. And they started yelling at each other and my dad said he can't believe I married him and just a lot of stuff. In the car I was trying to calm my husband down by saying my dad is just old school and traditional and my husband yelled at me saying I always make excuses for him and that my dad treats him and his kids like shit and I just make excuses. I don't mean to make excuses. It's how my dad is. I married a very untraditional man and I'm not traditional myself. My dad just sees things differently than us. I think my husband is just mad my dad called my bonus son weak but it's only because he has a different idea of what a man is.
