What is your purpose for answering questions on here?

i asked a question a little while ago and i realy like that someone answer was "For gods sake put some punctuation in there first!". First off i'm very sorry that i'm not that good about putting punctuation in, my bad (i kind of feel its a waiste of time, sorry my opinion). With that being said i would imagine if someone asks' a question for help with lifes problems the last thing they ant to hear is someones ignorant comments. It's not that im upset personaly about the comment I just want to tell people that if you dont like what you read on someones question for what ever reason, with the exception of hate crime related questions. Why would you anser with an ignorant comment? Please keep them to yourself because i would imagine that alot of people who ask not necissarily so good questions about life on here are already in a low enough place and could probably realy do without ignorant answers. I can't tell you what to do but i can ask if you dont have anything helpful to say then please keep all other comments to yourself
