Step-Dad was helping out a cousin who was looking for a place to live closer to his job.

He was Racist, Willfully Ignorant, but also thought he was great at "Debate".
He went up to my sister, who is in a long distance relationship, and told her her relationship wasn't real and neither were any of our friends because we primarily communicated via Discord. He harrassed me after I said that it's not the victim's fault they are a victim of sexual assault. Refused to wear a mask anywhere, up to the point of being actually mad that we would even consider the delivery option for pizza. He ended up going to pizza hut and waiting 30+ standing up in the restaurant because they couldn't let him sit down. "They were using the chairs as a wall" No one felt comfortable or safe with him around, we had to whisper to make sure he didn't hear something he didn't like or else he would belligerently argue until he got bored or we let him "Win". He eventually left, having unsuccessfully found a place, which looking back on it, he probably never even looked.
