ujm, I never said you should say Hallel on Yom Ha’atzmaut. I am personally very against it. I do think, however, that it is worth recognizing. I believe I said I was in favor of putting up a flag if you’re in Israel.
As for a hat and jacket, I never said I’m against it. I’m against saying that someone without a hat and jacket obviously isn’t a yaarei shamayim. You don’t know the person at all, yet you’re judging him based on how he dresses?
