Reddit is very big on not forcing people to become parents. Every thread about a woman cheating and the OP had a kid with her at least all the comments are about getting a paternity test, people think it's totally not an accusation of cheating if your demand a paternity test when you have an unplanned pregnancy in a long term relationship, and recently misinformation about how to abolish your parental rights in the US has spread like wild fire. (it's probably more like one crazy person on AITA, I don't make it a point to remember names)
You need a third party to take on the rights, don't sign consent forms to be recognized as the legal father if you are unmarried, and no because your ex said she wouldn't come after you for child support but now you are being sued doesn't make her a two faced bitch, it's more likely she filed for state assistance and state filed the claim. The state wants two parents to buffer the cost of the assistance they provide, they won't just let you go "welp I signed all the forms to claim this child as my own, but I don't wanna be a parent anymore
". It would be blatantly hypocritical if reddit did not extend their pro get-out-of-parenting-free belief to apply to women.
The only times they get on fathers who don't want to be so is when they guy admits to not using condoms or the child was born of an affair. Yes it really does suck that married couples have automatic assumed parentage, but that also (may) extend to married same sex couples. The latter doesn't have much information on as gay marriage in all states is still new.
