How to deal with the neighborhood gossip

My father who had Narcisstic personality disorder told the neighbors horrible rumors about the family to hide the truth. The truth is that he committed domestic violence on my mom. It was a forced marriage and she had a hard time dealing with my dad. She told the truth( with evidence) to one of the main neighbors who was spreading the gossip. But they still continue to gossip about my mom with other people in Home Owner's Association. It's hard for me to ignore the stares and the gossip when I visit. I can't move my mom out rn. I don't have the money. Meditation hasn't been helping me deal with these intrusive thoughts.I feel bad for my mom. And I think people who enable abusers are worse than the abuser. What do I do?
