Is it weird to call a Acura tsx a Honda tsx?

Im a girl and i've been slowly learning about cars and I called a Acura tsx a Honda tsx, and my friend (hes a guy) called me stupid for saying that and made a smart remarked by saying "how about you go buy a acura civic" And then claps. It made me feel embarrassed. So was I wrong?
