This is the reason my parents got me a Tracfone a couple years ago. I didn't really begin to start appreciating it until all of this stuff was brought out into the open.
Just ask yourselves this: Are you really okay with some creeper's eyes looking at your girlfriend naked over Skype, that girlfriend that you just might be married to one day, that person that has been a virgin for several years and has never even kissed somebody until you came along? That person who has given you the honor to be the first to see her naked and that you're so protective of that that you would kill anyone who tried to rape her or loveually assault her or even try to see her in a bathing suit?
Yeah, with this information, you won't be the only one looking at your girlfriend naked anymore. You won't be the only person in her life who has seen her naked, and you won't be able to defend her because you don't KNOW who has been watching and seeing parts of your girlfriend that is YOURS and only YOURS to look at. One day, this could escalate into touching, and feeling, and eventually, loveual abuse and rape from government officials in a quiet prison somewhere far away.
Do you really want to let these things happen to your special person in life? This is just an example for you to think about. Most of you probably haven't met this person yet, but just think about it for a moment. Doesn't it make you angry in the slightest?
Privacy matters. What you're doing is letting the perverted little boy in your girlfriend's yard take photos of her in the window while she's undressing in her room and fap to it in his own bedroom at home afterwards.
Privacy MATTERS for reasons other than security.
