“If you need to make an obscene gesture at someone for a Mitzvah , you lost whatever zchus there is for the mitzvah . There is never permission to do that. it was a tremendous Chilul Hashem that picture “
Classic diversion.
A worker was being harassed he flipped the terrorists “the bird” (I guess that is really sort of appropriate :0 ) and that is what YOU think is the Chillul Hashem.
But making a tummlt wuith the media and all while trying to stop a long standing minhag yisroel does not bother you.
You have some really mixed up priorities.
