Naturally nobody will happy when he or she is been criticised but for me I don't see it as a bad act I see it as a way of correction and it also encourages me to gain more knowledge about it.
We are all here to learn and gain more knowledge about Bitcoin and cryptocurrency when u are been criticised try and outline those mistakes you have made and learn from there don't see it as a mockery instand take it as an advantage to correct your error and move on
That's probably the right attitude about it, but I would still say that higher-ranked members shouldn't criticize newbies but they should adequately correct them and make them understand their mistakes, this way, they wouldn't feel bad or think that they are being criticized just because they are not having a high rank.
If I see a newbie making a mistake, I would correct them and tell them their mistake, but doing that in a bad way would make them feel not welcome and I would never want to do that though I understand that people generally don't want to make them feel bad but some users might do it in a harsh way.
