If I find people really hostile and offensive, I put them on ignore. Especially people with an overall "angry" attitude--I just avoid them as I am triggered by anger.

There are others who just seem very touchy, and I fear I will rile them by posting in their thread, no matter how careful I try to be, so I just don't post in their threads.

Some people don't like it if you post comments in threads they started that are not 100% on point to their original post. I like a more wide-ranging discussion, so I also try to avoid these threads for fear I will annoy the OP.

I too sometimes edit my posts to be more benign and supportive. I wish the period we had available for editing was greater than 1 hour. I also try to ask myself carefully (but I sometimes forget!), is the person posting for information or for support (or both)? If it seems they just want support, I try not to fill my post with "helpful" information. Just an empathy statement will do it.
