You make a pointless argument e.g. States can reasonably regulate parenthood, yes. -- Prohibit, no.
HOWEVER we are discussing here one things that prohibit naturally and factually both parentood and subsequently the rational premise underlying what makes a marriage legitimately recognized as such -the possibility of procreation.
ONLY by detaching from reality in discarding rational basis does your argument appear legitimate.
The argument you attempt to advance is a fallacy -an absurd illogical construct: e.g the State can not prohibit men from becoming pregnant...
ONLY by ignoring the biological reality of procreation which is the rational basis premising marriage does your argument "seem" legitimate...
P.S. repeating the absurd ad infinitum adds no legitimacy. IF you have an additional argument -then cough it up...
You need help.
Encouraging procreation and normal marriage is unconstitutional!!!
