Why do men who complain about single moms also advocate for men's right to abandon their kids (Financial abortion) ?

I see a lot of men complain about single moms saying that they are a problem to society, that they cost welfare money, that the kids Don't grow well without a father around , that dating a single mom is wrong because it makes you a cuck…and at the same time I see a lot men advocating for Financial abortion,even though the best way to tackle this "single moms" problem would be to force men to raise their own kids.
