The short answer is "no", at least in regards to those ex-JWs who are atheists and/or agnostics.
Vanderhoven7 in at least one way the Jehovah's Witnesses are much like the ancient religious Jews of the Hebrew Scriptures, in that the JWs believe they have the only true religion and the only true form of worship. The Jewish Hebrew Scriptures teaches that pure worship of Yahweh Elohim (aka, Jehovah God) is the only true worship and it teaches that the religion of the Jewish Hebrew Scriptures is only true religion. Micah 4:2 of the Jewish Hebrew Scriptures says that Gentiles from the around the world will worship Yahweh at his Jewish temple during the reign of the Jewish Messiah. Micah 4:2 (NIV) says the following.
'Many nations will come and say,
“Come, let us go up to the mountain of the Lord,
to the temple of the God of Jacob.
He will teach us his ways,
so that we may walk in his paths.”
The law will go out from Zion,
the word of the Lord from Jerusalem.'
Zechariah 8:23 (ASV) says the following. "Thus saith Jehovah of hosts: In those days it shall come to pass , that
ten men shall take hold, out of all the languages of the nations, they
shall take hold of the skirt of him that is a Jew, saying, We will go
with you, for we have heard that God is with you." Zechariah 8:23 (Douay-Rheims Bible) says the following. "Thus saith the Lord of hosts : In those days, wherein ten men of all
languages of the Gentiles shall take hold, and shall hold fast the shirt
of one that is a Jew, saying: We will go with you: for we have heard
that God is with you."
The JWs also worship the same God of the ancient Jews, namely Yahweh/Jehovah to the exclusion of Jesus Christ.
Also note the following. The Jewish scriptures (such as in Daniel) say a Jewish Messiah (worshiping Yahweh/Jehovah) will rule over all of the gentile nations. The JWs say a 144,000 JWs will rule with the Jewish Messiah (Jesus Christ) over all the Earth and the JWs say Jesus Christ worships Jehovah as God.
The WT's JW religion gets its idea of exclusivity from the Jewish Hebrew-Aramaic 'Holy' Scriptures.
Much of the core of the problem of the JW religion comes from the Jewish Hebrew-Aramaic-Greek Bible itself and its portrayal of a Jewish concept of a God of vengeance who demands exclusive devotion and strict obedience. Those ex-JWs who reject engaging in such worship are thinking and acting sensibly and are no part of some religious cult.
