good comment..
note that this is really for religious jews to comment on..
people that know the lingo.
The article is more political than religious why put restrictions on who should comment. Here in NY Rav Kahane Z''TL was very well known in all circles and still is. I think it would be great if all our members left positive comments on the article praising the Rav.
the readership of that website are religious jews.
If others are writing comments then it can look like a joke, I don't need to spell out why. (And imagine if it gets into discussion i.e. "re"), then it will really show. People reading articles on that website, including the comments are a certain audience
