Logical fallacy.
The welfare support of this homeless lesbian has nothing to do with whether or not this guy donated his sperm and for what purpose.
By your reasoning, do all other sperm donors have to pay for child support also?
“In most states, such as New York, the best interest of the child is considered before allowing a genetic parent to surrender their parental rights and obligations. If the parental rights are to be surrendered to the mothers spouse or partner, courts will likely allow that surrender.
However, if the mother is a single parent and no one else is assuming the surrendered parental rights, then the known donor cannot surrender those rights. This means that the known donor may be able to sue for custody and visitation rights, and the mother can sue for child support.
But What if I Have a Clearly Written Contract That Relinquishes All of My Rights?
Even if you have a written contract that attempts to relinquish your parental rights, a court may enforce full parental obligations upon you. It is the job of the court to uphold state law, as well as consider what is in the best interest of the child.
This is not to say that you should not have a written contract, because you should have a detailed contract outlining parental intentions. Consult an attorney before doing anything in the direction of becoming a known sperm donor.”
