I'm still in though mentally out. It's good you're pointing out those things, because JW claim to be superior in applying them. I now know that:
1. God has a name but it's not in the NT, so it's not obligatory for Christians to use it non stop.
2. JW aren't the only ones preaching, effectiveness is up to debate (they have success in developing world, not so much in developed countries)
3. This was something that always bothered me when I was 'studying' with the JW - if love was the 1 identifying mark; i knew many churches whose members were really much more approachable, loving and out there to help each other.
4. It is not clear if we're living in the last days, even if we are, these days are definitely not 'deep into the end, start your countdown' like the JW teach. The earth will surely have an end scientifically speaking.
5. JW base many of their beliefs on their current interpretation, which is open to change. They take from the Bible what they'd like to see there.
