Personally, whenever I see people going round and round in vicious, erratic cycles, I'm always wondering:
1. Does this person possibly have mental health issues? (What would a bi-polar cycle look like in written words, and am I witnessing one?) Are they not taking their medications or can they not afford treatment, and is this the result? I don't mean this in a judgmental or critical way, but rather, I then realize there is absolutely nothing I can say or do to reason with this person. If they've already made up their minds that it's everyone else who has the problem, not them, all one can really do is pray for them.
2. Does this person have a substance abuse problem, and am I seeing the effects of it in their writing? I often wonder how many posts, no matter how intelligent the person is or claims to be, are written in between gulps, smokes, and empty cans/bottles. Again, I'm not saying this in criticism, but as a reminder to myself that some people seem unreasonable because whatever it is they're doing in life makes them that way, and arguing with them is pointless.
3. Does this person have any regular contact with the outside world at all? Do they interact with people beyond the internet? I always personally think it's important to remember that many people online don't have much meaningful contact with other human beings, and I think this makes them much less sensitive to the thoughts, feelings, or needs of other people.
This isn't always the case, of course, but in so many cases, they're very isolated, and so even if they use all their time to study the Bible, all they know is themselves... and feel justified in condemning anyone who doesn't act, think, or speak as they do. Because they spend so much time reinforcing their own beliefs, they see themselves as Valiant Defenders of God's Truths and justify everything they do.
This is why I primarily stick to Singles. Sure, some of us here might be a little off our rockers
, but at least it's in a fun and lovable kind of way (for the most part.)
