It might also surprise you to know, OP, that according to the UN's own statistics (not that I'm a fan of the UN), around 85% of women and girls in Egypt have undergone female genital mutilation (FGM). But no one ever mentions it, for some reason.
Further, the UN Office of the High Commissioner for Human Rights (OHCHR) report on South-East Turkey estimated that between 355,000 and 500,000 people, mainly of Kurdish origin, were internally displaced during security operations in 2015–2016. The report also raised concerns about killings, destruction of housing, restrictions on movement, and lack of humanitarian access. Again, no one's cares.
Both countries have really fucking dodgy human rights records. And yet, if there are obnoxious, loud, angry, belligerent marches clogging up central London every other weekend over either of them, I must have missed them. If only I could put my finger on what this selective outrage is all about... but it just escapes me. 🤔
Never mind, I hear Pride in Tel Aviv is pretty damn good, so I'd tell the attendees of the cruise to give that a try instead.
