When my neighbour (man, 65 years old) died a couple of years ago, I went to the Protestant funeral, and the priest told that in my Father's House there are many rooms - one for playing with Barbie dolls, one for playing with electric trains, one for playing soccer - yeah, so much for respectful funerals. I sat there feeling ashamed that I call myself a Christian and hoping the others attending would not think I also believe such bullshit.
The JW funerals I have attended have been 90 % good. The non-JW funerals have been mostly bad, but a fe have been good. One excellent was held by two so-called "street priets" (working among addicts, homeless, and one excellent was held for my father, by a leading protestant Bishop.
So as with most things in this world - generalization is harmful.
