On toxicity in forums

[JunseiKei]

I thought it was having power.

"Nearly All Men Can Stand Adversity, But If You Want To Test a Man’s Character, Give Him Power"

Abraham Lincoln

“Power tends to corrupt and absolute power corrupts absolutely. Great men are almost always bad men, even when they exercise influence and not authority; still more when you superadd the tendency of the certainty of corruption by authority.”

Lord Acton

As said before
1. Internet
2. It's a static written format – there is no nuance or tone and a conversation with many voices not in real-time.

By all accounts this is one of the better behaved forums I've seen.
You can generally judge how a thread is going to go by the title and topic – some are clearly more incendiary than others but again, the FFXIV forum seems pretty tame overall.

Pretty much this. Unless people know your particular mannerisms in typing and word choice to your own personal lexicon, people may take offense for something that was not meant to be offensive.
