Based on their post history, I strongly suspect the OP has English as a non-primary language.

While I believe your intent and attempt is noble, in OP's comment history we find their admittance to being American.

Furthermore, I'd argue their history actually suggests that they're very much capable of writing perfectly sound English. In fact, this isn't my first interaction with OP. So I know they can do better. But, for whatever reason, they haven't demonstrably shown the same diligence when writing up this particular post.

They are doing fine, their posts are perfectly understandable.

The bold part is probably directly targeting the "proofreading your writings before posting them"-part of my original comment. And I'll admit that I should have done a better job at conveying that this doesn't intend to allude to a structural problem. So, to be clear, it was meant as general advice after being bothered by (only) this post.
