There is no conflict at all, of course there is separation between the office and the individual, the morality of the individual plays no part in the Sacraments he confers.
How can ordaining women be a proof of validity? (I have looked in vain for a meaning of 'down-check' and haven't been able to find one in even in the Urban Dictionary. Please, try and use terminology which English speakers worldwide understand).
The Catholic Church has declared that it has no authority from Christ to ordain women. Are you expecting Him to come down from heaven and grant them this authority?
If these non-Catholic ecclesial communities have no valid male priesthood, how can they possibly be taken seriously when they 'ordain' women.
You have hit a brick wall here.
