&gt; Trust me, the kidded people want to be able to hang with friends like the kids weren't a factor, but it's _so_ hard, and the only ones that actually do it are almost always super crappy parents.

As a "kidded person", I agree with that.  IF you are going to invite me somewhere, it's really hard to make it work if the kids aren't allowed.  It's possible, but it's expensive/requires asking family to babysit.  

Or I could just be a bad parent, as you pointed out, but screw that.
