I understand that, but what I am saying is that it is what is going to be about as well. Why is it even common to think that is automatically harassment because you are starting a conversation with a woman in a street or grocery store?
Generally, yelling things to women from a few meters is not starting a conversation.
I wouldn't say it's automatically harassment to approach women in public areas but you should be very careful about how you are doing that and be ever more polite. Most women want to get from point A to point B and not be picked up.
I didn't say anything about any yelling. I don't know about you, but I don't expect to pick up the women I talk to even if I start the conversation out of a sexual interest.
