The only thing that matters is truth.

'Antisemitism!', 'Racism!', 'Islamophobia!', 'Transphobia', or more generally, 'Hate!', etc., are essentailly meaningless
and seem to function in the same way that 'That's Heresy!!!' did in the (fast returning) Medieval Dark Ages.

They appear to be used to shut some argument/conclusion down (there's even a vague threat implied) before it can be examined/understood,
almost always in order to safeguard some lie and/or prevent some truth from being revealed.
