Since it was indiscriminate violence that spurred the protests; i guess the answer is, yes

The protests are pro-Palestine. Calling them pro-Hamas is just the pretext for shutting them down.

I’m not sure you are asking in good faith, but the answer is resoundingly Pro-Palestinian. There may be Hamas supporters in those protests, but you’ll have to look very hard (or more likely stretch [in bad faith] your interpretations of protest slogans) to find their message.
