Flags in Synagogue

Igros Moshe (OC I #46) Question  There is a synagogue in which there are two flags set up one of America the other of Israel. Because of these flags there are people who refuse to pray there. Is there any genuine problem with having the flags? Answer  Assuming that this is a shul that was constructed properly to have the holiness of a shul and people have already prayed there assuming it was holy. Even if a serious sin were done there or a degrading act it is not profaned and lose its holiness because of that even at the time the sin was done.  As regards to the question of losing its holiness after the sin it depends. If it is used immediately after the sin to pray as a holy place then there is no loss of holiness. Consequently even if you want to claim that the flags are sinful it does not lose its holiness because of them. It is better to pray there  than to make a minyan in a secular place and it is treated as any other shul. However I don’t understand what sin you think is being done by these flags? There is no prohibition to bring non holy objects into a shul even if not needed for the shul. This is true even if not built as a shul and surely if it were built as a shul as ours are.  This is true even if the flags were erected as a sign of the state of Israel by wicked people. Nevertheless, the flags are not regarded as holy objectsthat might be cause to be concerned for idolatry. They are simply a sign and are clearly secular. .  .  This is true also for the American flag. The flags are merely showing appreciation of Israel and America.  Therefore while it is better not to have the flags there permanently especially not next to the aron Kodesh. There is no actual prohibition being violated as it is clearly not idolatry but only nonsense. It would be best if they could be removed in a peaceful manner. But if that would cause fights  it is clearly prohibited. Therefore a new minyan should not be made for those who object to having the flags. It simply an issue of politics brought about by the yetzer harah and Satan
