WIY, if only we knew for sure why Hashem is sending these Gezeiros. All we can do is guess and try our best to improve.
Personally Im no fan of movies or slits, but I think Lashon Hara and ruining others’ reputations is far worse, which you mentioned after the other two.
Let’s throw into the mix the feeling of indifference that many have in regard to the bitter tears cried by older single girls. The relative time spent on shopping for adults’ and kids’ clothes, etc. and the gym, versus redding Shidduchim, by people who say they have no time to red Shidduchim. Sad.
I cant say for sure what Hashem despises most, but neither can anyone else.
