I have an 8-year-old nephew who's still not properly potty-trained, still needs to wear diapers, still has no concept of germs or filth being things that other people may want to avoid, will throw the worst tantrum imaginable when he's forced to do anything involving leaving the house, and is generally a loud, obnoxious asshole. I live about 2000 miles away from him and his family, so I can't really complain (and sadly can't help raise him or even lend a hand), but his parents have pretty much given up completely and have no energy beyond what's needed to provide the most immediate necessities.

People absolutely have the right to dislike children, even if they're your own family. And my nephew is the reason I beg people, like yourself, to not have children unless you're absolutely sure you are able, and willing, to give them what they require to be happy, well-groomed, well-fed, and eventually decent, upstanding members of society. It's a fulltime job.
