First, about profile pictures. I honestly don't understand how anyone without a profile picture can expect someone to be interested in them in an informed way (which, to me, is the only way). People are visually oriented, especially men, and this man wants to see what the person he's dealing with looks like. You can certainly see what I look like, so uploading a photo of yourself that shows your face is only fair! We all (guys) want to see what you look like. It would be good also to have one that shows your whole person, head to toe.
As for my photos, I know some of them are fairly dated, but I really haven't changed much at all in appearance over the past 8 years or so. A bit more gray hair and a few small under-eye wrinkles is about it. I'm usually not very photogenic -- cameras seem to catch me with stupid facial expressions, or with my eyes wide open like Count Dracula or completely shut, in the case of flash photos -- so I'm just doing the best I can with the few good pictures I can find. Not trying to look better or younger than I really do.
The last thing that ladies might want to know, since I've seen that this can put people off, is that I'm definitely a 'gun guy'. I own a number of handguns, rifles, shotguns. I have a concealed handgun permit, and tend to exercise that right where legally allowed when out and about. I don't hunt...vegans don't eat animals, so there's no need kill them, for food or sport. But I do see a need to have firearms around for the protection of family, friends, neighbors, and oneself. Target shooting's fun too; I used to take students out to the range every now and then, and they enjoyed that. The present point is that if you're uncomfortable around firearms, we probably wouldn't make a good match, unless you're willing to learn about guns with the goal of 'making friends' with them. I've seen people do that whereas they were a little skittish previously.
Does the Bible address this issue? Yes, in a lot of places. One train of thought that has spoken to me goes like this: Paul said that Christians are Abraham's spiritual children; Galatians 3:7,29. Jesus said that Abraham's children should "do the works of Abraham"; John 8:39. And Abraham took up arms to protect innocent people, including his kinsman Lot; Genesis 14. Melchizedek, "the priest of the most high God", blessed Abraham for his efforts, and Ellen White wrote positively about Abraham's actions in Patriarchs and Prophets, pp. 135-136. So the protection of innocent people (as well as oneself) from violent thugs by force of arms is definitely sanctioned by God, contrary to what some Christian speakers would have you believe! The Lord expects us to do some things for ourselves, as we're able, in His strength with His protection and guidance.
I'm all about safety when it comes to firearms, just so you know. Very careful, very cognizant of the weighty responsibility that comes with having them around. But anyone who's around me is safer as a result, when it comes to being a victim of crime. My neighbors know this, and they're glad for it.
