I don't doubt that divorce courts are occasionally biased in favour of the mother. However, the stats presented in the manosphere are often misleading. A lot of divorced men don't even want primary custody of their kids. A lot of couples always delegated 90% of the parenting to the mother and keep it that way after the divorce.

It's also very "convenient" that male suicides are highlighted by the manosphere, but female suicide attempts that are much higher are dismissed as "women wanting attention".
