It's already done it. Outside sources have often contradicted them. I don't have them all on my fingertips as I never knew i'd need them to debate with enthusiastic type of Bangladeshis on a forum, but from what i've read & heard and seen ground realities, i'm confident these are heavily exaggerated. I only believe in stats that make sense. Period.
70% of Pakistanis marry their cousins? LMAO what a joke. You'd think we wouldn't have made have made it past 200 million people if the majority of us are retarded.
It's like those claims that majority of Chinese eat dogs just because a few idiots there do. China would not have reached a population of 1 billion if the majority of them ate dogs.
Likewise i think minimizing cousin marriages in bangladesh to 5% is a huge downsize. Bangladesh ain't Iceland where people use apps to ensure they're not dating relatives.
