I'd say you posted a bit too much of it. The long string of insults at the end does nothing to support the point raised in the beginning, and probably upset people.

It's a fair criticism to say that perl culture encourages code that is tricky, sneaky, or magical in some way, and that tendency has consequences on how people view perl and perl programmers. It's quite a touchy issue though, as you can see whenever someone suggests that writing simpler code would make for easier maintenance and then gets attacked by people saying that there's no point in toning down code for people who don't know perl well enough.

I'm not sure the author here chose a very good example. This one looks like someone who didn't know about fancier things like IPC::Open2, not someone trying to be tricky. He's right about combining statements with "and" though.
