Zero chance that the white dad will be on the hook for the black baby within .0001 seconds of that paternity test being opened.

Really depends on the state (if he lived in the US.)

For all the hate that liberals, feminists and woke warriors (especially on Reddit)  have for "men's right movement" or "men's right activism" (MRA), a major accomplishment of MRA is that nowadays most states would let a husband off the hook for child support if paternity tests can prove that he is a victim of paternity fraud and not the biological father.  

I remember that, back before 2000s and in the 1980s and 1990s: in almost all states, a husband could still be forced to pay child support  for 18 years even if the baby was obviously not his, (for example: the baby came out a different skin color,) as long as the baby was born inside a marriage to the woman to whom he was was married, he was legally required to pay for child support.   Furthermore, even in states that allowed husbands to challenge paternity fraud,  most of those states set narrow time limits for how long a husband could challenge the baby's paternity.  

I am no longer part of the MRA, (it tries to wholesale too much other right-wing ideologies that have nothing to do with men's rights,) but I have followed its crusade against paternity fraud over the decades.  MRA's big contribution is that it has really done away with both those unreasonable conditions for fighting against paternity fraud, (i.e., a husband is automatically responsible for a child birthed by his wife in a marriage, and an unreasonable time limit for how long the husband can challenge the paternity.)  Of course, DNA testings (which were not affordable nor accessible to the public before 2000s) have also greatly helped MRA to challenge laws and policies that protect women who committed paternity fraud.

Unfortunately, other than that one accomplishment, MRA has mostly been infested by right-wing extremists and women-hating chauvinists.  I got into that movement to fight paternity fraud and for men's right, but then the movement has been increasingly taken over and dominated by conservatives and Republicans. They have tried to wholesale the entire conservative ideologies to every MRA member, (i.e., ideologies that have nothing to do with men's rights and do not interest me,) which has driven away a lot of men who are interested in men's rights but not right-wing conservatism or extremism.

However, even a broken clock is correct twice a day, and the progress and successes against paternity fraud is one of the few instances for which MRA has been correct and successful.  (Liberals would have never tried to challenge paternity frauds that protects women; in fact, they have worked actively to fight the MRA to protect the frauds.)
