"I excuse the typos as your eye condition is probably the reason and it would be crass to mention them so I don't, I just work through them."
How you could take that as stooping to any sort of level (even though if it had been it still wouldn't be anywhere near the bottom as most of yours are)?
It was not an insulting thing to say, I was just stating a fact and why I don't mention your typos so stop trying to make out it was said in any other way than it is written above.
