What? It's "Doesn't bother me" however you look at it. Because it uses elipsis. The full sentence would be "[This fact] does not bother me" where "this fact" refers to all the things that he means, i.e. "typos, spelling errors, grammatical errors and nonsensical sentences."
Just like he said, "Do not bother me" would make no sense, except the case where you'd use the multiple subject to highlight what you mean. So it would be "The typos, spelling errors, grammatical errors and nonsensical sentences don't bother me." Otherwise you default to the singular that encompasses the whole. I have studied linguistics. Please tell me how this is wrong, oh self-appointed intellectual that runs circles around the simple mortals.
So the full sentence would actually be "The fact that typos, spelling errors, grammatical errors and nonsensical sentences are present does not bother me." It's nobody's fault that you can't make a simple correlation, but at least don't correct others when you have no idea what you're talking about.
You could use "Those don't bother me." This would also be correct. But they way he said it is also correct. So you attacked him for no fault of his, just because you wanted to feel superior on a porn website.
I'll probably not see your reply anyway, since I log in here once in a blue moon, but I felt like replying.
I do agree with your other point.
