1. This journal is my virtual living room. Welcome. Please act as you would in my home. 2. The internet is made up of real people with real feelings that need respecting. 3. Everyone has a right to an opinion, even if it differs from mine. As long as you state your opinion without impinging on the right of another person to hold an opposite view and are respectful of them as people, you are fine.
This concept needs to be really clear, so I'll give you an example. Fine: I believe that my politics/ cats/ my straight needles are better than other politics/ hamsters/ circular needles and they are all I will ever, ever use or believe in. Not Fine: I believe that my politics/ my cat /my straight needles are better than your politics/ your hamster/ your circular needles and if you don't think so too, then you are stupid.
