We have different perspectives. If some tours have skirted dress requirements for temples, mosques, and churches, this doesn’t make it not disrespectful. In the case of Istanbul and the Blue Mosque, I am Muslim and have prayed in these mosques. There is one dress requirement for entering any mosque in the world, there is no minimum requirement for visitors. All are welcome, however, there is a dress requirement. We can agree to disagree on this.
