I don't like the idea of frightening anyone. It's kind of easy for me to do accidentally just because of my size. Back in the phase where I dressed like a biker, there were several occasions where women actually screamed when suddenly faced by me, e.g. trying to go through the same door from opposite sides. I've also had my permit to carry a concealed firearm for a long time, since back in the day when people got really upset if they knew you had a gun. It was best to be super careful lest friends be worried if they found out.
It's one of the contributors to my submissive kinks. Begging for footjobs seems about as nonthreatening as you can get.
I posted anonymously once and somebody replied addressing me as Mousie. I thought that was kinda funny and certainly not very threatening so I went with it. As Mousie, my big fear is making someone think I'm a cyberstalker. I'm a Christian, which means I fit the profile of a villain from the Law & Order franchise. I'm separated from my wife, lonely, and my programming job was outsourced to India in this recession so I have a lot of time on my hands. I'm super aware that that perfectly fits the profile of stalker. Or, it just means a lot of time to hang around reading and commenting on people's blogs.
So I try consciously not to say anything that could create the impression of romantic or sexual interest, and I try to occasionally work in lack of interest hints, without it being a PUA-style challenging "neg" or an insult. E.g., X would be totally bored by my sexual preferences. I'd like to say more nice things to the people who are lightening up my day, but don't dare.
Actual predators have a whole series of tricks that are intended to look inoffensive on the surface, but aren't. "Give me a smile, baby." I don't know many of those, but the people reading me do. Which is really worrisome; since it looks inoffensive, will I do it by accident? I'm walking on eggshells. I blame it on the predators, and I have unchristian hate for them, and if I express that I sound scary for unfortunately much more true and accurate reasons (at least if you're a predator). EDIT: Not genuinely true and accurate, but definitely closer.
