spongeypop - you seem to have some seriously weird FB friends. if I were you, I would unfriend them immediately.
I also have several FB friends with kids on Israel tours and yes, they're obviously all worried. What parent wouldn't be?
None of the Jews or Israelis I know on FB express sentiments of hatred towards Palestinians in general (Hamas is not flavour of the month, I agree, but this is understandable).
You seem, in all your posts, determined to stir up hatred towards Jews/Israelis, that is based on entirely false premises.
Do your supposed FB friends know you feel this way? If so, why are these mythical people friends with you, as you don't appear to have anything in common and seem out to slander them at every opportunity?
Seriously, if you have friends who are so callous they don't care about their own children's safety and hate people they've never met because they live in a foreign country, then you've got really, really, really bad taste in friends.
