Could I suggest the following would be worth thinking about :
1. Be nicer to each other.
2. Be more tolerant of each other.
3. Where mistakes are made in factual terms, politely correct them without snark or sarcasm.
4. Where opinions are disagreed with - remain pleasant whilst stating the opposite case.
5. If you can't say something nice about a fellow forum member, then best not say anything.
6. Remember this isn't just a forum visited by enthusiasts. It is also read by people working in the industry (who may also be enthusiasts)
7. Think about who is reading your posts, and how they would feel when reading them.
8. If you DO have dyslexia or another issue that may mean your posts look unusual or are difficult to read, then it might be worth putting something in your signature. A couple of colleagues I have at work who have quite severe dyslexia have a standard part of their e-mail signature that mentions it to avoid people thinking they are being disrespectful by rushing their replies. (And not everything can be picked up by spell check)
I know we're all guilty of getting caught up in personal opinions, enthusiasms and obsessions at times (and I'm sure I've been guilty of not doing everything I suggest above) - but you know this forum would be a lot more pleasant to visit if people on it were a bit more pleasant to each other.
If I'm honest, some of the conversations here amount to little more than bullying at times.
