This is nothing to do with hate.
There are very strong hashkafik disagreements between many sects and chabad. (-really?!
) For whatever reason, Chabad always had an interest in selling/trying to influence others to their derech and hashkafa. -Arguably this is what the parade idea was all about.- Satmar and others are entitled to raise their kids al pi their derech without the kids having undue influence from other mehalchim. When I was growing up, we were also warned very strongly not to go near the chabad parades which were designed to entertain and entice kids....
Not trying to start a chabad bashing fest, I just don't think that satmar is so out of line here at all.
