I despair of making this perhaps too subtle point clear.
I do NOT think it is wrong to approach women in public. I have done it myself. Where my misgivings begin is when one begins to see the activity not as a normal part of life but as some sort of separate activity that requires learning special skills etc. I think looking at it that way has an impact on how a guy thinks of women.
Let me try my own analogy. Some people, including me, enjoy drinking a good wine and have picked up some knowledge of wines casually in various ways through their lives. Other people take drinking wine so seriously that they study wines and develop a sophisticated understanding of all the factors that influence wine and how best to enjoy wine etc; they become wine connoisseurs. Both types of people drink and enjoy wine, but they think of and experience wines quite differently. Imo, neither way is good or bad because wines are not people and how we think of and treat wines has no impact on their welfare or feelings (because they have neither), but not so women...who happen to be people.
Maybe that helps a bit?

I prefer a "wine connoisseur" with the right attitude
