This view is pretty common for people reading their first language written by someone using their second or third language. This comes people that just isn't as good at writing and expressing themselves. This does by no means make their thoughts less valuable. Sometimes you just have to open your mind to other people even though the words come out in the wrong order.
English is not my first language either but I don't write "I'm sorry for my mistakes, english is not my first language" because that should be pretty obvious. And if it's not obvious, there is no need to say it, right?
I just think I'm fortunate that my first language became the de-facto language for technology and that anyone who speaks/writes it well enough to be comprehensible about technical matters in a 2nd language deserves my respect!.
My GF finds that I know multiple programming languages impressive while not realising that her ability to speak English, Hungarian and German fluently leaves me in awe.
