Great question. IMO; some of negativity in profiles is easily explained by group behavior theory…but not for the guy with no short answers - and I’m not a sociologist, just a fan.
Above all other traits, we humans are social animals. We’re not hermits, we’re groups, clans people, tribes, nations, with unifying languages, dialects, and different flags with distinctive close-knit groups like the Boy Scouts, Kawainas, Republicans, Democrats and Swingers.
We create and join social groups throughout of lifetime because they give us our culture and norms and our identity. They give us the ability to be recognized members of our group in a blink of the eye in a crowd; suit and tie versus blue jeans and t-shits, bikini vs one piece, side burns or flat top, shirt in or shirt out all define us visually. The other powerful way we align with groups is through inclusion and exclusion; or "in-grouo, out-group" and the feelings that we belong to a group, or we don’t fit in.
In-groups and out-groups commonly have disdain for one another and their defining thoughts of others are “not like us. ” This ends up as sexism, ageism, homophobia, and judgements here on SLS about entire cultures, races, sexes, and sexual orientation. And when we’re looking for sexual partnerships the thinking continues to finding someone "like us” and staying away from others “not like us."
“HWP only,” "BBC only," "straight guys only,” “no open pictures means…” are all positive affirmations to the mind of the in-group, and I suggest that they don’t represent a negative thought to the minds of it's "not like us” members. They either forgot how to catch flies with honey, they’re unaware they're negative, or they know better and they don’t care. I’ve seen all three examples in this forum.
What I appreciate the most about this forum are the positive norms of the culture in here. There’s a passenger van of regular interesting authors in this forum who convey positive, sincere, help with plenty of thoughtfulness and humor in their answers - and their questions; thanks for this one sorillo. That cultural tone comes from the moderator GGMM and her style of shining a light on the negatives and offering positive alternatives - that’s so appealing to folks wanting to learn how to improve their profile. It also follows that the regular contributors are following her tone of sincere, genuine, helpful, humorous, thoughtful and kind.
So I present you two separate environments; the positive one here where everyone’s admiring the leader, following her lead for positive communications and "profile land” where there's a shit storm. The more profile reviews that happen, the more positive profiles we’ll see.
