Chatting up a stranger is not 'borderline harassment'. Harassment is harassment. There's a correct way to approach someone in a non-threatening manner, and more men should take the time to learn how to respectfully strike up conversation with strangers (in both romantic and non-romantic contexts)

Given the cultural norms around dating require men to initiate the conversation 95%+ of the time, there's a real risk of demonizing men's efforts to initiate conversation. If nobody approaches, then a lot of great connections never get formed.
