Advice taken, though as mentioned, I do feel that some assumptions were made not just by me, but by others in regards to my intentions and tone (perhaps not as much in this thread, but in others; I admit I was rather frustrated in posting here and thus, was a bit rude at times). I'd pull the "and I'm only 19" card, but I really don't think age is an excuse for hot-headedness, though perhaps it could account for my lesser degree of experience working with people. Oh, forget it; I'm not going to write off misconduct that is probably just part of my personality.
It is very easy for things to become heated when discussing animals, especially on a medium like the internet when we aren't face to face with a human being, the individual is an absolute stranger (and are thus unaware of what level of knowledge the possess), are unable to assess the situation in full, etc.
I also am starting to get the feeling that cultural/locational differences have an impact on how advice is interpreted; I've noticed in general on forums everywhere, non-US citizens are often more offended by my tone than US citizens, likely because we're not known for being polite in this country.
Very sorry to hear about the brain tumors! That can be quite a frightening ordeal, though it sounds like you had good medical professionals. I was diagnosed with bran lessions last year and that alone was quite the scare.
And, I do agree, this is an interesting debate for a Fish Forum.
edit: also, just as an afterthought - I think one of the reasons I come off as condescending is that sometimes we have to be in dealing with clients; you'd be amazed at the number of people who don't even consider things such as "you need to adjust a dog's collar as it grows" or "don't feed chocolate to your cat" etc. Darn, only one year down and they're already doing a darn fine job of training us to talk to everyone as though they are imbeciles.
