I very much doubt that the biological value has anything to do with it (as in the "absolute", evolutionary biological value). I think society evolve much too fast for that to be a lingering vestige from when that would actually matter in an evolutionary sense.
The complaint isn't about "my friends wanting to make sure I get home safely", it's about "my friends thinking I'm unable to make sane judgements, and take care of myself -- unlike when I was a child and was afforded equal consideration to my male peers".
You doubt that the fact that a woman has to be pregnant for 9 months to have a baby (risking her life, too) whereas a man just needs to spill sperm for 10 seconds has any impact on society today? Well you only see what you want to see, is all I can say to that...
As for the complaint about caring friends, that seems to be all in the interpretation and is one good example of why I reject feminism: it seems to be all about negative thinking and feeling like a victim. You COULD think "hey it's nice that my friends worry about me" but instead you think "ugh, my friends think I am helpless and irresponsible". That's just a negative, miserable, useless attitude, sorry.
I didn't say I didn't think it had any impact on society. I said I doubted it had an impact on "it"; "it" being how young adult males and females are perceived in society today with a view to self-reliance and independence.
Well you kind of turned the issue around - why is offering to go home with somebody a challenge to their self-reliance and independence? I would have thought it is about safety and common sense. In the worst case it gives you one more option (go home with a companion), which would make you effectively more independent?
