To correct and tell newbies what to do when they’re doing the wrong thing should be perceived as teaching them about the do’s and don’ts of the forum even if they get merits through that. You can’t conclude that by correcting them means that they’re bullying them and should not be done in that way. This is a public forum and each person have their own way to correct, judge or direct someone. The day you stop perceiving every correction, critics as bullying, you’ll have a smooth ride in the forum’s journey.
We are taught to be friendly to everyone, but sometimes the language of writing is very difficult to understand, even if you feel attacked, sometimes that is not the intention of the writer who is attacking. Maybe if you see and meet in person it will be a little different. In fact I think everyone who started felt that way including me when I first joined this forum. We all just have to understand everyone has different styles and good intentions. We just have to get used to it, because I'm sure the people who give advice are the ones who have good intentions.
