You're a guy that's convinced himself that walking around shopping centres asking girls if you can tickle them is a normal and healthy thing to do while simultaneously trying to pass it off as some masterstroke of social interaction. Your implication apparently being that people are either out there "living life" like yourself, or "sat behind a computer monitor" like anyone who criticises what you're doing?
Even if I give you the benefit of the doubt (and based on your responses so far I don't see a reason why I should) and assume that you only approach girls over 18, are polite and direct with your requests, and leave people alone rather than harass them, the ratio of people who go "sure why not?" and acquiesce versus the number of people who you are going to make feel extremely uncomfortable and creeped out is skewed so far into the negative that I wonder why you'd bother with this scheme rather than just behaving like a normal human and treat women like they're actual people. The conclusion I come to is that you just don't give a shit about the people who you upset, which is why I feel I'm able to "judge" you, as you put it, based on the small amount of information I've currently seen.
e: genuine question, how many pick-up artist forums are you a member of?
