Reasons:

  1. For men, it doesn't succeed most of the time.

  2. Men would have better chances meeting women through friends, or online/app dating.

  3. Cold Approaching plays into Rape Culture. Most women do not like being Cold Approached, because they see it as harassment.

  4. Women will publicly voice their displeasure of being Cold Approached, and this rhetoric further diminishes the success of Cold Approaching, and further reinforces the notion that Cold Approaching is a part of Rape Culture.

  5. In conclusion, Cold Approaching doesn't benefit either gender.

Disclaimer: Obviously Cold Approaching has worked for a minority of people, but they are the exception.

I highly recommend starting off this debate with your definition of what constitutes a "cold approach."

For "Cold Approach", I am using the most broad and simple definition of it, that is: Cold Approaching is when you attempt to flirt with a stranger, whom you know little or nothing about.
