Both chants could be seen as pretty insensitive, but I'm not having that supporting Palestinian rights to live freely in what was their land is the same as denying Israeli rights to do the same.
Anti-Semitism has become weaponised by the state of Israel in an attempt to suppress any criticism of their actions towards Palestinians, and it's been going on for a while now.
Calling out for a ceasefire in Gaza is not supporting the atrocities committed by Hamas and nor is it Anti-Semitic.
As for Rememberance Day, unless people are planning protests directly against it, I can't see an issue. I lost family in the great war too, as did many here I'll bet. I've got closer family and friends who served more recently.
It bothers me not a jot if people elsewhere are marching for peace. The point of one of those wars was to maintain our freedom, not least of expression.
What I'm less keen on is either the far right claiming the flag for themselves, or fetishising the military. That is a dangerous path to follow.
