Firstly arranged marriage & forced marriage are two different things (i worked in Slough for 8 years, where forced marriage and honour-based violence was prevelant...but not necessarily the norm).
Secondly, yes, don't say anything to a woman you wouldn't want The Rock, your prison inmate, your rapist / abuser / domestic violence perpetrater (men can be victims too you know) to say to you.
There is absolutely nothing wrong with talking to a stranger in public, being nice, friendly or approachable with others. The problem starts when you aren't nice, friendly or approachable ie you act like a d**khead around other people; whether you're male or female. EVERYONE deserves respect - that's it. Respect people first, be a Harvey W type (or paler comparison) second, when you know you've cleared it with that person that they consent to that.
