All to often the closer the beliefs the greater the hate.

In terms of the same deity - Jews, Christians and Muslims, and all the different sects within those religions, all worship the same deity.    they just disagree about who Jesus was - false messiah, messiah, prophet.

How much blood has been shed by these groups and internal sects killing each other?

Religion can really f-k people up.

During the last evening that Jesus spent with his apostles before his death, he reminded them: “A slave is not greater than his master. If they have persecuted me, they will persecute you also; if they have observed my word, they will observe yours also. But they will do all these things against you on account of my name, because they do not know him that sent me.”—John 15:20, 21.

It was not merely isolated instances of intolerance that Jesus had in mind. Just three days earlier, he had said: “You will be objects of hatred by all the nations on account of my name.”—Matt. 24:9.

Yet, Jesus counseled his followers that when faced with persecution, they must not resort to carnal weapons. (Matt. 26:48-52) They were not to revile their persecutors or seek to retaliate. (Rom. 12:14; 1 Pet. 2:21-23) Might it not be that even those persecutors would someday become believers? (Acts 2:36-42; 7:58–8:1; 9:1-22) Any settling of accounts was to be left to God.—Rom. 12:17-19.

It is well-known that early Christians were cruelly persecuted by the Roman government. But it is also noteworthy that the foremost persecutors of Jesus Christ were the religious leaders and that Pontius Pilate, the Roman governor, had Jesus executed because they demanded it. (Luke 23:13-25) After Jesus’ death it was once again the religious leaders who were in the forefront as persecutors of Jesus’ followers. (Acts 4:1-22; 5:17-32; 9:1, 2) Has that not also been the pattern in more recent times?

JW's have substantially different beliefs, as to the true nature of God, compared to authentic Christianity. Hence, fraternal correction, rather than hate, is the order of the day.

Hate comes from the hater and not that which they chose to hate.

True Christians do not hate anyone, since Jesus Christ commanded us to love our enemies and to do good of those who persecute us. It isn't hatred to say that JW's have rejected God's truth, and are living by the teachings of their founder instead of the teachings of God. It's just the objective truth.

Because they knock on your door in the middle of Wheel of Fortune.

I certainly don't hate JWs.  When they come to my door I engage with them and they leave with a smile on their faces.  They don't worship the same God as Christians do, though.  God is the Father/Son/Holy Spirit, not Jehovah who sent a mere archangel for their salvation.
