And you have always denied the Israelis carried them out

I have not.
Not in 1948, just in the last half century or so.

you even went as far as to claim that Benny Morris's claims of 27 Israeli massacres were "disputed",

Everything he has ever said is disputed Jim.

I have never at any time pretended that massacres did not take place on both sides - you, on the other hand, have always done so,

I have not.

Proper little massacre denier, aren't you?

No. I just expect evidence.
When will you produce some?

Put up or go away

I will willingly "put up" but what Jim?
You accuse Israel of massacres and atrocities but can produce no evidence for it.
I "put up" Israel's side of the story, and you have not been able to challenge anything.

You should "put up" or stop making accusations you can not substantiate.
