Not very alpha thing to do to hide a secret wife cause you're scared how the wife will react
no need to equate polygamy with secret wives.
The principle of Polygamy is pure and if practiced properly is Halaal.
Blood transfusions if done incorrectly cause STI, should all blood works be outlawed?
Same applies to Polygamy.
Why demean something made halaal by Allah.
a woman can refuse and has a right to refuse being in a polygamous household.
But don’t try to upgrade the Deen like an iPhone ios software
