English is nothing more than another vehicle humans use to communicate. For you to claim using proper grammar and well formed sentences of the english language is just a cop out to the point the OP was trying to make. Let me paraphrase in a grammar that is perhaps closer to on par with the level you seek: "I have spent a long time on hacker news.

you're right, I appreciate the honest words. i'm just having difficulties in being serious - this is a personal trait and part of my very way to learn since it enables me to stay distant and see more of the bigger picture, thus not easily changed.

For shorter posts, it is probably worth your time to spend an extra 1 or 2 minutes making sure the capitalization and grammar are correct.

There's a HUGE difference between a native English speaker writing a thoughtless post with bad style, and a non-native English speaker writing a thoughtful post with bad style.
I think a lot of HN people are sensitive to writing style because it's a useful way to decide whether or not you should bother reading something. If a comment is very poorly written, it is more likely (but not definite) that the content is also poorly imagined.
The problem is when there are "false negatives" such as yourself--people who are carefully thinking through their ideas, but are not as well-versed in writing style. Help the community cut you some slack; advertise the fact that English is not your first language when you do not have the time or skill to make your posts perfect. :-)
