From my own point of view (I have two young daughters) it matters not whom they talk to on the net, be they male, female gay or straight. It is the 'intent' that is important.
I have less problem with them talking to gays (male or female) than possible 'perv' grey mac straight guys. The main problem is how do you know which is which anyway.
