There’s different levels of support for Palestinians. Some are reasonable, and others are not.
Calling for Israel to reduce it’s impact on civilians is reasonable. I saw a protest yesterday at my local mall where people were laying on the floor covering themselves in sheets to protest the killings. That’s pretty reasonable in my opinion.
Unfortunately though, the majority of (almost 3 in 4) Palestinian civilians in Gaza support Hamas’ attack on Israeli civilians on Oct 7th that killed over 800 innocent people. reuters.com/…/poll-shows-palestinians-back-oct-7-…
Being generically “pro-Palestinian” though is essentially saying you’re okay with what they support, but not Israel’s response. I find that to be unreasonable.
