Ok, you wouldn't want to train with me based on one forum post. That pretty much tells me all I need to know, but...
I am totally respectful, ask anyone who actually knows me.
I'm not into bowing because it's not something I've ever done. I would bow if I was in a country where it was the normal thing rather than shaking hands etc. I would bow in a dojo if the instructor wanted people to. I don't think there is a need to force bowing though and I think that anything which is done because of a rule loses any sense of being respectful.
Foul language - it's just words. What people mean is more important than the words they use. I have told people not to swear before because kids were present. If it's just adults about, I really don't mind what people say.
Unwritten rules where I train are;
- be respectful to everyone
- train hard
- maintain a good standard of cleanliness
Other stuff is obvious like removing jewelry. I would count speaking to the instructor if starting late/leaving early under being respectful.
