Question on port matching

What I see is a lot of is this.
"Fred" ridiculing "Sam" as a fool for believing what "George" has to say. Then "Fred" tells "Sam" that what "Fred" has to say is in fact the truth. Usually accompanied with a lot of personal attacks about how much smarter "Fred" is than "George". Followed by personal attacks from "George" about how much smarter he is than "Fred". Then "Carl" and "John" each pick sides and join in.
All justified as trying to help Sam make an informed decision.
Why are so many people angry?
What you’ve posted Reminds me of working on a construction crew years ago, bunch of different companies crews slapping up houses in a subdivision. One crew taking a break looking over at another companies crew on a house criticizing, ridiculing and mocking amongst themselves how that crew was doing things, even though it was legit, yielded the same results. Human nature. Sometimes the posts here are akin to drive-by posting, road rage posting, guys throwing snowballs at the cars passing by, dropping a Boulder from an overpass...:steering:
