Damage Reduction and On-Hit Effects

Quote from MPA >>

 I literally responded that they don't suffer any conditions because it doesn't hit them.

I'll agree that you said that. You were wrong (reducing damage to zero does not mean the attack does not hit), but you did say it.

The OP’s question was about whether the Monk still suffered non-damaging effects of an attack if the damage was reduced down to zero, not about whether such effects would be applied to the target of a redirected attack.

 I literally responded that they don't suffer any conditions because it doesn't hit them.

If by “them”, you mean the Monk, then that’s incorrect, for reasons that have already been quite well explained.

If by “them”, you mean the creature the attack was redirected to, then that’s correct, but not what the question was.

By them yes the Monk, doesn't suffer any conditions. And yes I am correct.

You are not correct. Reducing the damage of a successful attack down to 0 does not turn it into a miss, nor does it have any impact on other non-damaging effects the attack might have caused. This has been explained in this thread multiple times; I suggest you read through the rest of the thread.

 That is incorrect. I've already stated my reasons to support My position, which is correct. I think this dialog has come to its conclusion

Your reasons have no basis in the rules of the game. The Deflect Attacks ability never says that the attack misses if the damage is reduced to 0. Once you are dealt damage, you have been hit and the ability only reduces the damage and does not reduce or negate any other aspect of that hit. If you expend a Focus Point, you direct some of the momentum into a target, but that is a new attack (offensive act requiring a saving throw, not an attack roll) originating from the monk.

When you reduce the damage to 0, it doesn't even declare the attack as deflected, which wouldn't have mechanical weight even if it did. The attack remains a hit.

You are incorrect and it may help if you reread the ability more closely.

Deflect Attacks

When an attack roll hits you and its damage includes Bludgeoning, Piercing, or Slashing damage, you can take a Reaction to reduce the attack’s total damage against you. The reduction equals 1d10 plus your Dexterity modifier and Monk level.

If you reduce the damage to 0, you can expend 1 Focus Point to redirect some of the attack’s force. If you do so, choose a creature you can see within 5 feet of yourself if the attack was a melee attack or a creature you can see within 60 feet of yourself that isn’t behind Total Cover if the attack was a ranged attack. That creature must succeed on a Dexterity saving throw or take damage equal to two rolls of your Martial Arts die plus your Dexterity modifier. The damage is the same type dealt by the attack.

These are the actual rules. You have made claims about what the rules say but haven't posted the rules so here they are. They do not say what you claimed they say.

You have to be hit to use the ability. It reduces the damage but never turns a hit into a miss. If you redirect the attack, you are redirecting some of the force.
