I am not judging you ad-hominem, but You are incorrect on many counts here. The purpose of these people flying to Israel was as a protest; an attempt to make a big deal out of it. Israel lets thousands through the airport every day; nothing makes those thousands different, except for the fact that they are not trying to delegitimize Israel (if you don't believe me, refer to the picture from the article. People holding up signs reading "welcome to palestine" in ben-Gurion airport are definitely not respecting even the recognized borders of israel) and cause problems for the state. I am sure hundreds go to Israel to get to the palestinian territories, without any problem.
