Telika: Unfortunately, things are being drowned in the stupidity of antisemitism and islamophobia, which both instrumentalize the israel/palestine conflict a lot. A lot of antisemits claim that they are merely against israel's policies, and a lot of supporters of Israel's colonialism claim that criticisms are just antisemitisms. So, all these forms of racisms (in the broadest sense) make debates very confused and confusing. You basically can't trust anyone's stance to be devoid of some driving underlying antisemitism or islamophobia, and everyone exploit this.
So, to cut a long story short, what you're saying is that the anti-semitic wankers have jumped on the bandwagon of claiming to only be criticising Israel's policies so that they can gain some kind of legitimacy. That certainly wouldn't be wrong.
I don't know (many) people who have a problem with Jews (although I grew up in a strongly right-wing region, meaning that national-socialist sentiment does raise its ugly head), but then most reasonable people draw a distinction between Judaism, the Israeli people, the orthodox settlers and the Israeli government.
The latter two are essentially directly (albeit only partly) responsible for the shit that's going down. The Israeli people are indirectly responsible through their election habits - first with Sharon, then with Netanyahu, although, as I understand it, the West Bank situation played only a very small part in the election campaigns (maybe someone like ET3D can shed more light on that).
Judaism as a whole doesn't really factor into it at all, unless you also wish to blame all of Islam for Hamas or al-Qa'ida (and ironically, many of those resorting to accusations of anti-semitism are indeed themselves quite islamophobic - pot, kettle and all that).
And yes, Hamas is the other responsible party. What you have here is not "Israel" vs. "Palestine". What you have here is Jewish extremism vs. Islamic extremism. Hamas and the extreme Zionist elements of Israel (which Benyamin Netanyahu is essentially a frontman for) are just as bad as each other, which is why genuine advocates of peace in this conflict are few and far between.
Like most reasonable people, I have no beef with anyone based on their creed or race. But I will not condone people thinking that their religion (or lack thereof; I have equally little tolerance for fellow atheists who seem to have nothing better to do than mouth off about religion being the root of all evil) gives them carte blanche to act like cunts.
