why do so many discussions turn contentious?

just venting....why do so many discussion posts need to turn  contenious and nasty?  do you guys find that constructive and/or enjoyable?  I have no clue who or how this forum is moderated, but I sure would love to see a stop to that...it makes me feel like this hobby is dominated by total jerks.

Can't we play nice, share OPINIONS and OBSERVATIONS, realizing that  they often are subjective and biased.  
"if you dont have anything nice to say, say nothing"?  If you wish to disagree, do it in a constructive and mature fashion, no need for "argument ad hominem"...

with all the chaff, one must waste so much time finding the wheat, figuratively speaking.  

I doubt my writing this will change anything, but, like most social media, people writing to others without facing them does not bring out the best, sadly......

Not a lot of people are truly nice.
The world was never that way. This site is not any different.

Social media can certainly put a stark light on our fragile egos. I’ve had a few people go at me here. I have thick skin so I mostly just feel embarrassed for them.

But there’s a lot of useful information here and some wisdom and some great humor.
It keeps me interested.

I will say this. And I hate to say it. The behavior on this site, is worse than most.
There are lots of jerks everywhere....why would this site be any different? Coincidentally, there have been a few videos posted to you tube about audiophile jerk/snobs just recently.
I think the pandemic definitely is one contributing factor, as people are venting their building frustrations that COVID is nurturing.  Another reason is that for decades, the world in general, and the U.S. more specifically, is becoming less of a "WE" society and more of a "ME" society, and More and More, MY opinion, MY rights, are becoming more and more important that YOUR rights and opinions. And, if you disagree with me, you are a blankety blank S...O...B...who deserves the wrath of Hell brought down upon you.  Okay, that's a bit of an exaggeration, for now at least.  But you catch my drift.
It's "gasbagism," where pretentious "experts" assume everyone thinks they're a genius and they weave anything into the conversation that supports this self obsession that only the truly insecure can display. From injecting whacky politics to yammering about how cool they think they are in their personal world with unassailable taste...sort of pollutes  the stream.
It's one thing to stick up to get the honest truth against some of the "snake oil" products here and to warn against them, but to start just slinging s**t at each other for no reason
That's the pot calling the kettle...
What you refer to is 'your truth' George.

I suggest you get off your high horse; you are not our saviour. 
Or you could always continue slinging your bile, which you are renowned for.
