Slander is an untruthful oral (spoken) statement about a person that harms the person’s reputation or standing in the community.
Since this is an anonymous WRITTEN website you cannot be slandered.
Even it were not, I don’t think you can be slandered by WRITTEN truth.
Slander:
I am a Mormon. he is stating what Mormons believe, and what Mormons teach, therefore he is stating That I Believe and teach what he said. This is not true. What he said and the way he said it is not taught by the church. any more than orthodox Christians Teach that Jesus walked on the water because he was wearing special "Floating" shoes...
