I assume they are pro-Israel, but I do not see how it's obvious that they all are. Either way, it has nothing to do with what I said.
Again, what I said was: "Calling for ceasefires, accusing the IDF of indiscriminately bombing civilians, making excuses for the 10/7 atrocities and drawing a moral equivalence between Hamas and the IDF is not well intended criticism."
In any event, people with family members being held hostage that are calling for ceasefire are likely not doing it because they believe it's what's best for Israel.
