Right, we should have just said, “NY Post? Feh. Frum Jews don’t read that garbage.”
But the problem with making a big issue of it can be seen as if we don’t care about the actions (or alleged actions). Remember when Satmar had a huge fundraiser for a child molester? Actions like that talk.
In this case, once people start going all crazy, some people will ask, “but is it true?” And if so, why does the community not care?
As far as the name calling, you can see it here all the time, when YWN puts Lapid’s picture upside down, or Lipman is called a Rasha or YM”S. YWN moderates all posts. Why would they allow that through? If we as a society don’t care when people we disagree with are called Rasha, or Yimach Shmo, why should the NYPost care?
