I am glad to hear it. My journey to becoming a pilot was greatly enhanced by my online experiences, and I'm gratified that you have found a welcome here.
I think the vast majority mean well, but there are a peculiar few who, either by intent or personality, treat people badly. In my experience, these nasty few commonly share two traits:
1. A harsh writing style. These posters type whatever they are thinking. Basically, the filter that would prevent them from saying something verbally is missing when they write.
2. Poor reading comprehension. This has created more online angst than any other single trait, IMHO. Someone will say something innocent like "High wings are better for photography", and four posts in someone is accusing the OP of "hating low wings". It's crazy, and I've seen it happening more and more.
IMHO, this has driven off many good people over the years, both on AOPA and POA forums. I have no idea how to fix it.
