you seem to be trying to push a certain pov on the article please see wp rs for why info has to be sourced to be added it also works the other way around you tried to remove information that was backed up with reliable sources if it's not true surely there's a source and that information should be included alongside the allegations just removing it full scale with an edit summary saying it hasn't been proven and that it's slander which obviously you don't even know what that means isn't going to cut it you're going to need to cite your sources or provide a legitimate reason for removal otherwise you will continue to be reverted
