Either the person you're telling your opinion about Palestine agrees with you or not. Expressing an opinion about some situation publicly is not hate. And who you're telling your opinion to is irrelevant.

You're not telling them to not attack Palestine by shouting "Free Palestine", or anything similar, only that you believe that Palestine should be free, so your comparison is not valid, because it does not contain any hidden assumptions.

They might as well agree with you. They can correctly respond by shouting Free Palestine back at you.

Correct. Expressing your opinion about Palestine to the general public is not hate.

Directing the expression of that opinion at random Jewish people, in a targeted manner is hate.
