You should read some of my posts in which I criticise Isaiah and others as false prophets. If that's not a criticism of Judaism I don't know what is.I see nobody criticizing the Jews or their beliefs, it is always the Baha'is.
As for why Baha'is get more criticism, its because you tend to receive what you put out. It wasn't a Jew who started this thread criticising the beliefs of Jews - they are clearly on the defence here.
Sure there are some who pick on Baha'i because its the new kid on the block, but to be fair I've noticed that coming more from Muslims and 1 or 2 Hindus than from the Jews.
