I agree with you OP....
This isn't about naked pictures and totally inappropriate behaviors...
This is ALL about healthy personal boundaries.
IMHO, a teenager/young adult should be able to have a forum to share with likeminded friends without 80 year old Granny horning in.
What some people may find completely appropriate, others (like granny) may not.
And, IMHO, a granny who, in addition to calling almost every single day, thinks she should also be able to participate (horn in) in a teen/young adults personal 'SPACE'....
Sure, if we did have myspace, as a parent, I would occasionally moniter MY underage CHILDS page to make sure that nothing was dangerous or like way beyond appropriate.
Yes, this is all about privacy and healthy personal boundaries...
And, yes, it is the internet... But there are passwords, 'friends', 'blocking', for a reason.....
IMHO, it is perfectly acceptable, and even DESIREABLE for a teen/young adult to begin to establish their own friends and their own lives without the overbearing influence of 'conservative granny' horning in.
If dear old Granny wants to establish her own 'FAMILY' myspace page for easy family-wide communications... Then, let her have at it.
But, to
expect a teen/young adult grandchild to invite you in to her personal page as a friend crosses so many limits it makes my head spin.
