I think your opinion is irrelevant and based in ignorance of Islam and the values that a predominately Islamic society holds for its citizens. These are not easy or often flippant decisions made and/or accepted by people. But part of listening means accepting where you have a right to form opinions, to have them heard, and to feel entitled to them being relevant. This is not listening. This is you asserting a colonialist's supremacy on a culture that does not agree with your ethic. This same line of thinking is what led to the British invasions of Central Asia and Africa, that Indians were barbaric and Brits would bring the education and civil discipline to their land and improve their lives. Well, what good have yours and their Napoleon complexes left?

Different cultures have different views of acceptability. I am sure there are things in western culture that seem absolutely abhorrent to other cultures (one that comes to mind is killing infants after they are born, selling baby parts for money, and abortion in general). Having a view of moral superiority while perpetrating what other cultures consider atrocities, is, at best, the pot calling the kettle black. And at worst, being completely wrong. It is good to have a bit of leniency, civility, and trying to understand others when they disagree, even on subjects in which we are personally invested.

We should not conflate sexual freedom in general with the very specific kind promoted by Tinder. There are many different ways you could design the UX of a dating app and in my opinion the Tinder approach has some very serious downsides. Dating online doesn't necessarily have to be about promoting a lot of shallow and superficial interactions.

Western people are usually surprised to find out that people actually have freedoms outside of America and Europe. They just often choose to sacrifice more egregious ones for communal good than not.
