My boyfriend family acts a bit weird; is this usual?

For a bit of context, we are both 26, in our first relationship, and we met on hinge in June 2022; we made things official in August, and things are going great for us. My boyfriend is also adopted and mentioned this to me on our second date, and his parents are very much old-school Catholics.
I first met his mom in October 2022 during one of his recreational hockey games, and we chatted a bit. At this time, I also met his brother, and during that first meeting, I felt as if they were a bit apprehensive of me, and my boyfriend was quite annoyed at his mom, for the manner she had introduced herself and so forth.
The second time I saw his mom was during another of his recreational hockey games back in December and this time she was a bit more friendly; we chatted, and she even shared her blanket with me as I was a bit cold.
They had kindly invited me over to their home for Christmas this past holiday season, so I attended their brunch and dinner. During this time, I noticed the dynamic lol between his parents, as they seemed to argue back and forth, his dad called a woman on tv stupid as she had placed her shoes in a bathtub on an HGTV show, and then his dad was telling his mom, she drove like a woman lol, it was all this weird gender/misogynistic tone the entire time.
So the atmosphere was honestly so weird and then his dad just sat in their second living room watching TV the entire time and didn't really interact. They got me nice Christmas gifts but the vibe was so weird.

Anyhow, we are coming on our six months anniversary, and we are doing fine. Still, these are just weird observations I have made about his family dynamic, and I was wondering if this is usual.
What are your thoughts?
