You should also go help these people, they think ALL Jews stink.
Croats can't be helped, it's just the way they are. It would be like talking to an aggressive wall.
I don't think all Croats are like them.
If you go by that logic, then you could say not all Arabs hate Israel. I was talking in general terms, and the fact is that a huge majority of Croats are vicious antisemites, especially on that forum. They even have a thread called "Why I hate the Jews".
Also, I don't know if you are Christian, but maybe you are familiar with this saying: "Do not throw your pearls before swine, or they will trample them under their feet, and turn and tear you to pieces."
Those people are in the state of mind when you can't reason with them. Trying to have a meaningful conversation with those swines would only enrage them further.
