The trouble is people mistake members helping someone out to members nit-picking about tiny things.
Example:
Someone has posted a review of Balto 2 but got things a bit mixed up, a couple of people post correcting them and giving evidence why they say the person's post is mistaken slightly, the person isn't sure they're right and tell them, the members then post more saying what is actually right, the person edits their post and their topic is now correct.
On another hand:
Someone has posted a review of Balto 2 but got things a bit mixed up, a couple of people post saying "You've got it wrong, learn your facts.

" and the person feels a bit offended and upset and ask if instead of being rude they'd please point out what they'd got wrong so they can edit their post so that the information is correct but instead the people post back saying "No, do the research yourself and I wasn't being rude!!

".
Notice the difference?
