As discussed ad nauseum in threads passim, many threads involving the public descend into name calling or other behaviours that fall into the general category of "arguing with strangers over the internet" which has existed since message boards were invented.
Perhaps the solution is for us to contribute to such threads as if we were chat bots or call centre agents:
Questioner: Can I claim home to McDonalds as a business expense because the cafe I usually lunch at next door is closed?
Arthur (virtual assistant): Good Morning Anon, my name is Arthur and I will be helping with your query. What a great question! Before I answer please let me have some more information
A: I'm sorry, I didn't understand that
Q: Is my trip to McDonalds a business journey?
A: Please let me know, are you self employed, an employee, a director, or something else
Q: I'm self employed and proud of it, I have my own company which my wife and me and the boy are directors of
A: Are you self employed or are you running a limited company?
Q: YES how many times do I have to tell you?
A: What is the vehicle in which you travel?
Q: Transit van
A: And do you own the van or is it provided by the company?
Q: What does that matter?
A: I'm sorry Anon, your question is too complicated for me to try and answer here, I suggest you speak to a local accountant who won't mind you wasting their time.
Q: This site is rubbish, I expected proper thinly disguised sneering and patronising from a bunch of old saddos
A: Before you go, would you mind taking a short survey?
