I know what your talking about, it mostly happens to the newbies. It happened to me when I first joined. Some just think they know it all and this world is just too big to know it all, you can learn something new everyday if your open to it.
Sometimes I will even side with the newbies even if I don't agree on what they are saying. I will just agree with them because I hate when they all gang up on one person, I guess it makes them feel special, that they belong somewhere

. This one post just got way OUT OF CONTROL when this lady said she sells her puppies at 6 weeks. Where did all the attacking prove, the lady still got all her puppies sold and ended her membership here on YT.
When I see those kinds of posts now I just go to a different thread. V is right though those are the threads that get the most views but, although there are those crazy threads there is alot of good stuff and nice people here YT. I know I view them just see who are the most rude and think they know it all, so when I ask a question I will know who to stay away from.
I wish we could all just get along if you don't agree on something so be it explain it to the person in a way that is not rude and leave it alone, don't keep going back and posting rude comments. If the person starts getting rude after you nicely told them you did not agree then be the bigger person and walk away (or should I say go to another thread).
Sorry just had to vent along with you
