Rabbi of crawley- in my humble opinion, they don’t feel it’s wrong, rather they probably feel it’s ineffective and counter productive as sometimes protests strengthen the resolve of the opposition. I would imagine Charedim Rabbonim would agree with that assessment, but they would argue that they aren’t arguing for the result, but rather they are arguing simply to show that they disapprove and that they are against this- whether it’s Chillul Shabbos or reform or some other kind of public aveirah.
And that’s the question, is the purpose of these public protests to show that the Frum Jews do not accept this unholiness in our land and we will stand up for it, or are these protests for the purpose of actually stopping the unholiness and being mekarev the perpetrators? Charedim seem to prefer the former while Dati Leumi seem to prefer the latter.
