As far as I can see, the rudeness is pretty one-sided. Accusing people of DEMANDING replies to their questions, but then doing exactly the same is rude.
Asking a question, dismissing the answer but not giving an opinion as to what is the 'right answer' is rude.
Making assertions about science, then refusing to back them up with a 'go and Google it' is rude.
Asking the same questions (eg about whether someone should have to check genitals before deciding on their sex) over and over, then complaining when the answer is given over and over is rude.
Commenting on a post by saying that you haven't bothered to read it is very rude.
Telling people to 'go to other threads' is rude.
Calling people bigots is rude and offensive (and probably, as the culprit is very fond of citing GN rules 'against the spirit of Gransnet').
Accusing people of 'policing' the language whilst simultaneously redefining words that have been in the language for centuries and refusing to provide new ones is gaslighting, as well as being rude.
Making sweeping, unsubstantiated and offensive generalisations about groups of people is rude, narrow-minded and bigoted. (OED definition of 'bigoted' adjective:
adjective: bigoted
obstinately or unreasonably attached to a belief, opinion, or faction, in particular prejudiced against or antagonistic towards a person or people on the basis of their membership of a particular group.)
Etc. (those examples are just from the past couple of pages)
When you say 'bringing people's personal lives into it', do you mean things like questioning 'how much involvement [people have] had with the gay community', when it is clear that there is a very limited understanding of the way in which TRAs are anti-gay? That's about the only example of that that I can think of, but do point us in the direction of another if you can (or is that a DEMAND because it came from me?).
Swear words? 
As for respect - I have far more respect for people who can debate rationally and without resorting to childish retorts such as 'because I say so', and 'Who made you God?', who back up their assertions when asked for clarification, and who respond to other participants in the debate. I don't mind whether they agree or disagree, but I have no respect for people who do none of the above, but get angry and abusive when they can't (or won't) answer a question.
Oh, and happy-clappy nonsense about trees in forests is just patronising and adds nothing to the debate.
