There's affection and there's exhibitionism.

I don't mind people kissing, cuddling, holding hands, etc. But, if I see two people really going for it with the tongues, I yell "Get a Room!".. lol

I don't think there's any need for it to be honest. The only time I think it's acceptable is if someone is clearly saying goodbye to someone else. But if it's just a couple making-out on a bench in the High Street then I think it's for show.
