Support Israel?
Yeah, no.
For me, they lost my support when I learned they're just as effin horrible - and in some ways worse - than the "Evil" Palestinians. They lost my support when they started doing illegal things. They lost my support when I grew up and realized that all the "oh pity Israel" hype was BS.
They're no different than those they hate and revile and at this point deserve the condemnation and disgust they get. Israel has no superiority, moral or otherwise. They got their land on the back of world guilt and desire not to have them in X countries, NOT reason enough to support them.
If/When they change, I will support them again; until that time I pack them all up with the rest of the region. Let them blow themselves to hell since it's what they want anyway.
