I think it really depends on the individual....I personally do not think I should have kids, but I wouldn't be able to take care of them. Now I am not entirely opposed to the idea of falling into a relationship with someone and eventually making it official through marrige but would not want kids after the fact, though being a-religious don't know I'd want to do a whole church ceremony...but don't know I'll ever get into a serious relationship anyways.
But yeah I think it depends on the individual...the reason I don't want kids is not that I have a PDD aka ASD, but rather I personally doubt I could take care of them and quite frankly not sure I could even endure a pregnancy without risk to my health...I have trouble with being underweight, mentally I already got enough issues and from what I understand hormone stuff during pregnancy can make you even more moody, and I can hardly stand the digestive discomfort I get as is quite certain getting pregnant would make that worse so also physically not sure I could safely have children.
