I'm saying that chivalry is a small part of decent behaviour which refers specifically to men's behaviour towards women
Yes....and I've asked repeatedly (a) why we aren't being decent to everyone and (b) WHY.
Of course there are some behaviours or manners that are distinctly male, yes. You would take great umbridge at that, but I think most women would not. In fact, many / most women are attracted to these behaviours
Not at all. In my experience most men who display chivalry are "performance manning" - they're basically trying to say, "look at me, look how I treat women, how great am I?!"
I think you see being “feminine” as weak or inferior, but I don’t and maybe this is the difference
Definitely not. I'm feminine myself. But I also don't expect to be treated differently because I'm female.
Hold the door for the next person regardless of sex, take your turn, be patient, say "please" and "thank you". I'd far rather everyone did this, don't you think it would be more pleasant?
