If you don't see making false charges about critical issues problematic, then you have your own conscience to deal with before you debate with anyone else.
But when you make accusations as you have done without being able to back them up with facts, you need to be prepared to be challenged.
So far, you have avoided and evaded supporting your charges with evidence.
Most likely that's because there is none.
If it's 'arrogant' to care about the truth, consider me guilty as charged.
You are a boor. Go away.
