You probably mean "affecting". As a verb, "effect" means "to put into effect" or sometimes "to make more effective". Somehow I don't get the sense you meant either of those.

Some people really get sour when others politely point out grammatical mistakes they've made on a written forum. It's understandable as some people don't really do it tactfully and it can come across abrasive. Then there's a special kind of person who gets sour and snarky over someone politely pointing out grammatical mistakes other people have made.
