No it makes you look guilty for defending him. I've made that same mistake myself. My first game despite being town, I tried to call the person sussing me sus for sussing me. I also tried defending someone who was sussed. I then died D1 despite being town.
Perhaps things are different here, but in the games I've played it is never a good look to try to turn the sus on someone sussing you or to try to side with someone who is getting sussed. It's best to leave them to defend themselves.
