While I agree with Edward Horgan (Letters, January 28) that “perpetrators of genocide are often not held to account”, his comment that “many people are justifiably opposed to crimes against humanity committed by Israel against Palestinians” is disturbing.

The Palestinian Authority agreed under the Oslo accords that resolution of its dispute with Israel should be by direct negotiation and not via outside channels.

While Dr Kevin McCarthy (Letters, November 24 ) may well be correct that “Israel will respond to synagogue attack”, one aspect is not widely known.

While everyone is entitled to hold their personal opinions, however misguided, it behoves them at least not to distort facts in order to support them.
