Your comment represents everything that is wrong about a monoculture.
Bias against employing parents is bad enough, but any notion of hostility against an "other" is unwarranted. Surely the tech industry has enough room for people who have kids and people who don't?
Definitely not. But you said you preferred working in an industry that is hostile towards people with kids. Here's a thought experiment: substitute "people with kids" with the word "homosexuals" or "immigrants", and maybe you can see how someone can find your viewpoint problematic.
