@SFPW, I get what you're saying, and frankly, I agree . . . to a point. I agree that one should not go it alone, that they should be with others of like faith. After all, iron sharpens iron, right?
Heb 10:24,25 is often quoted to indicate meetings. That, frankly, is the WTS interpretation of this verse. However, this could also simply mean gathering together, even socially, with ones of like faith for the purpose of building up. You also used Matt 18:20, which says: "For where there are two or three gathered together in my name, there I am in their midst." There's a point of contention here. It's the "in my name" part. Who said this? Christ. JWs do NOT gather in Christ's name. Not at all.
What Does the Bible Really Teach, or brochures such as, Who Are Doing Jehovah's Will Today?, or the tract being featured in a current campaign, Can the Dead Really Live Again?, they realized that some if not all of their major beliefs were false.
I don't have that benefit myself as I was raised a JW. However, your statement is a strawman's argument. There are a lot of false teachings in other religions, and it's just as easy for a non-JW to expose falsehoods as it is a JW. Your statement does not address the fact that some of what JWs teach is or has been false, too.
Funny you should use the Ethiopian Eunuch as an example. It's one of my favorites since it took, what, maybe an hour, or even a few from study to baptism? No questions to go over. No special qualifications to be baptized. The man simply had faith and was baptized. How simple was that? To say that the person probably had a good amount of knowledge already so didn't need all the time necessary for people today is ridiculous. When one believes, one can and should be baptized, even if they don't fully know everything. Remember, they are baptized into Christt (oh, yeah... JWs don't baptize in the name of the Father, Son and Holy Spirit... nevermind this stuff then, it doesn't apply.)
Regardless, we'll continue to press on assisting that need help to understand the Scriptures accurately with the Bible based literature provided under God's direction.
If you insist. Just remember James 3:1. And remember to teach yourself, as well . . . not by relying on magazines that change their understanding of things every few years, but by really digging in for yourself. I implore you to do that... take off the WT blinders, READ the Bible, compare translations, look at interlinears, and most of all, pray for wisdom and understanding. Ask yourself: Why do I believe what I do? Can I prove, for example, that only the 144,000 are part of the New Covenant scripturally, and not with conjecture or speculation? Can I prove from the scriptures that Christ was enthroned in 1914, and did not become king after he was raised as Matt 28:18 indicates? Can I prove scripturally that there will be "new scrolls" that will tell us how to live life in the new system, or even what those new scrolls are? Can I prove by the scriptures alone, and without any words such as "evidently", "logically", or "we understand" that Daniel 4 has a secondary fulfillment leading to the 2,520 years prophecy and thereby to 1914? Am I so certain that the WTS is correct that whenever the NWT has words added or removed that they are being completely, 100% unbiased, and not led by their own theology (a term known as eisegesis)?
Best wishes for you on what may prove to be an interesting journey.
