I've never had an issue with being labeled as that-guy, but I don't game in the same 100'x100' spot day in and day out. I tend to do it as I go about my day, hang out with friends, go to Target or the grocery store or the greenways, etc. Sometimes I will deliberately pick hang-out locations with my friends that I know will have us in a place with good foot-traffic and a higher chance of hot young women being around. And as for reactions from on-lookers, I've yet to have anything other than a good reaction. Most women and men who stop and watch seem spell-bound, like they can't believe what they are seeing, and usually after an interaction, women (even grannies) often give me a look of, "I wish you would do that to me." Many guys just look and smile like "damn, I wish I had the courage to do that." But the majority of bystanders are oblivious to it and off in their own little worlds so they don't even notice and if the do they don't care. People really don't give AF.
Actually I take back my first statement - it did happen to me once. In another city while traveling, I did have one girl I approached ask me something like, "Are you one of those guys who is here to learn how to approach and game girls?" I just laughed it off and asked her if that was really a thing, and asked her if I seemed like that type. She said I didn't, said that people really did come there for that, and then I made a comment about how interesting it is that things have gotten to where they are today where men feel like they need instruction on how to talk to women, then I changed the subject and we talked about other things. But that also leads me want to mention that when I was learning day game and pick up, 99% of the guys I would see on Youtube seemed pretty fake in their approaches. Like, it was really obvious they were gaming, and trying to entertain. That's just never the approach I have taken. I've always just been real and authentic and tried to have a genuine conversation/connection with another human being (who happened to be a hot woman). The YT guys just seemed very ****y and "gamey" (for lack of a better description) right from the get-go. If I was a woman I'd feel like I was probably the 100th person he'd said the same thing to that day and would be annoyed. I very, very rarely get that vibe from women, probably because of my approach. I'm confident, but not ****y, and I am able to convey an ACTUAL honest interest in the woman, not just an interest in my pitch and banter. These guys are coming off like a car salesman. I never do that. I come off as a guy who saw a beautiful girl and was very curious about her and couldn't resist the urge to meet her and see what she was all about and who she was and then judge her to determine if I'm actually interested in proceeding with her. For whatever reason, the reaction I usually get is one of the fairy tail scenario that all women hope for - that chance encounter. And really that IS what it is.
