This is Hasbara. Most may be posting from outside Israel. That is Hasbara’s tactic. Keep repeating lies so an uninformed observer thinks it’s true.
Another tactic they have is to post numbers and revised history that most uninformed readers will take as fact, because who is going to check numbers and dates, and all revised history? All that gobblygook adds cred to the poster. No need to correct them they don’t care will just shoot you down with insults. That’s what they do when they are cornered.
