I agree but unfortunately that is what the majority of people do.

I, myself used to be extremely judgemental when I was in my early teens - but at that age who isn't?! I'm now not so judgemental, I do give honest opinions but only if I'm asked. Sometimes I'm told I'm too honest but I always say don't ask a question if you're not prepared to hear an answer you won't like. Maybe I could tone some things down but I'm not particularly nasty, I do try to put things nicely.

Obviously I get first impressions when I meet people and I used to judge people by that first impression but I've learnt not to. If I meet someone and don't like what I see, hear or feel I'm still friendly and polite and I take the time to get to know them without judging them.

I'm going slightly off topic now..
I'm sorry you feel you were wrongly judged and were made to feel bad. On the internet it is hard to read people and to interpret what they are saying...the way it's being said etc. so maybe they didn't mean to hurt your feelings or they couldn't write what they wanted to say without it sounding hurtful.
