Joseph,
Were you referring to me with the letzanus comment?
My sarcasm was referring to people who reflexively assur the muttar. Look at your own comments in the “owning dogs” thread. Things that are perfectly allowable you insist are forbidden. So if leitzanus means mocking those who distort our Torah, then I am guilty as charged.
Also, the comment about the zoo in Yerushalayim was completely serious. It’s a wonderful zoo. One of the best I’ve been to. I recommend it especially to those who have small children. It’s nicely spread out, but without the excessive walking in some other zoos (e.g. San Diego or Toronto). A real oasis of tranquility in an otherwise busy city. It’s close to Malchah.
