I see there has been a bit of a row:
The right to defend yourself against terrorist attacks, whether foreign or domestic is enshrined in international law.
Asserting Israel’s right to defend itself doesn’t mean you support genocide or that you agree with Israel’s government’s shock and awe scorched Earth tactics that kill tens of thousands of civilians and go beyond self defence.
The right to resist military occupation is also enshrined in international law.
Asserting Palestine’s right to resist occupation doesn’t mean that you support terrorist organisations like Hamas or Islamic Jihad or that you agree with these organisations’ terrorist tactics that kill thousands of civilians and are an illegal method of resistance.
I presume certain posters did cross the line from asserting rights into supporting genocide/terrorism and so were deleted.
But let us not tar all those who support the legal rights of Israel and Palestine with the same brush.
