We see this perversion with Hezbollah too. Hezbollah keeps attacking Israel, but when Israel strikes Hezbollah many commentators, and even some western politicians (e.g. in the Belgian government) are pretending that Israel was striking inside Lebanon for no reason.
Hence there are multiple possibly valid interpretations as to what is being reference.
No, there aren't. "Resistance is justified" right after 10/7 is the clear reference justifying Hamas (aka "Islamic Resistance Movement") murdering Jews. There is no other valid interpretation here.
It is entirely possible that different flag wavers were referencing different things. I don't dismiss that there were supporters of Hamas and terroristm
Yes, you are pretty much dismissing it by pretending that there are different interpretations of these banners. By the way, what is your apologetics for "from the river to the sea" slogans?
but I don't dismiss that there were protesters who are supporting the Gazan civilians and their struggle to remain alive and uninjured.
I am sure there are some, but they are not waving banners with references to Palestinian "Resistance".
Another photo from the same 10/8 protest:
"By any means necessary" is pretty clear justifying Hamas terrorism.
"Free all our prisoners" including murderous terrorists like Abdullah Barghouti who is serving 67 life terms.
"Stop the US-Israeli war against Palestine" is particularly rich given that Gaza started the war.
I wonder what apologetics you will have for these banners.
Just like I don't dismiss that there those who support Israel who root for genocide
Who for example?
