It's confusing to mix up this specific incident with the general dislike toward ElAl.
The parent-child analogy is obvious baloney because no (good) parent takes to the blogs to insult his child (see the OTD thread for more info). I love this blog and these forums but it's obvious that some people have a personal gripe/anger/frustration with the airline, that may or may not be rooted in good intentions, but the posts reflect accordingly.
There's the sugya of how to deal with large corporations who act against our own best wishes and another sugya of "hoche'ach tochia'ch" of how to tell off a fellow Jew for a misdeed. The two are obviously different, but can become confusing when we do this kind of stuff all day.
