> I really dislike the suggestion that someone who didn't attend college is therefore unable to write.

That's not what he said. He suggested that someone who doesn't write well probably didn't attend college.

> Your writing is not strong, i can tell you did not attend college.

Maybe you're right but this is how I read it.

Alice's writing is not strong -> Alice did not attend college.

therefore

Bob's writing is strong -> Bob did attend college.

You just fell into a logical fallacy. https://en.wikipedia.org/wiki/Denying_the_antecedent

On the other hand, what the other user deducted was:

* If you attend college -> You probably end up writing properly

* OP doesn't write properly -> He probably didn't attend college

Which is a proper logical deduction rule called modus tollens. https://en.wikipedia.org/wiki/Modus_tollens

I apologize in advance for nitpicking, but since this sub-thread is about usage: it should be "deduced" not "deducted."

Thanks for telling me, English isn't my first language and I often make mistakes. I can't edit my comment to correct it.

Fair enough! Happy to be proved wrong :)

They teach you English writing in CS/STEM programmes?

Often, STEM programs require out-of-major courses relating to written or spoken communication. Even if that isn't required, I would strongly advise all STEM students to cultivate those skills during their schooling.

Comfort and expertise reading, writing, and verbally communicating in English are some of the most important skills that distinguish excellent software engineers I have worked with and hired.

In many cases, those skills are even more important than technical/coding expertise--it's easier to teach and learn technicals when one's student is a fluent communicator, but a programming genius who routinely fails to explain their decisions or creations is a liability.

Somewhat ironically (or perhaps regrettably for the US education system), most of the engineers I have worked with or hired who were the most impressive written/spoken readers/communicators were people whose first language was not english, and many of the folks who struggled were native speakers/writers.

Edits: grammar, ironically.
