Whoever makes a nutty claim, has the burden of proof.
(If the OP was not just trolling, because this forum has plenty of examples of "what is wrong").
But you can try with this one:
"Islam is a totalitarian religion* and the basic rext has remained unaltered since the iron age"
*it tells you how to sleep, how to wash, what to eat, how to dress, how to have sex (and with whom). It is permeated by a fixation on sex, reducing women to livestock that must be covered up and not be left on their own, lest they stray or get stolen, and it reduces men to mindless horny animals, that must rape anything female not covered up in three black cloth sacks.
(Black thick clothing under tropical temperatures.... How is that for "stupid"?)
It fucks up the economy, by telling one gender that they are superior and really don't have to care as long as they pray, and by considering the other gender mindless livestock primarily suited for domestic work and breeding.
It also fucks up economy by imposing an entire mont of eating disorder every year.
... Not to mention disturbing the sleep and work with five daily prayers.
I know a guy who does economical modelling (macroeconomics). When they forecast economic growth they have some pretty good models. If the country has islamic rule, the expectations are lowered with a dummy, to make the model fit the real world. "Islamic countries just don't work as well as any other country".
It fucks up the educational system (look under economics above, basically for the same reasons, but also because it limits the range of acceptable topics and that it makes critical thinking an offence).
People who are critical, apostates or just too secular are routinely persecuted or murdered. Quite a few countries have that in their official laws, or are surprisingly unwilling to make any real investigation in the cases.
It even has rules, regulations and the correct prayers for taking a crap!
