If that's not what you were talking about, then WTF IS the alternative to "forcing a man into parenthood" once he's made the decision to get a woman pregnant?
Are you seriously making the argument that a decision to have sex means that society can blithely tell a person "Sorry - you should have thought of that before having sex"?
Once again, gender is immaterial - if you're willing to say that people who have sex should stand by their decision to risk pregnancy then you're going to annoy a large number of people.
The only way your argument can work is if you bring gender into it - try making whatever argument you think you're making without referring to the gender of the parent-to-be.
The minute you toss out gender considerations the arguments for/against forced parenthood fall apart.
