Letting people prance around doesn't make a right either. But it's okay for them...seems legit.
Usage of this forum is a service, the providers of that service and their representatives have sole discretion for determining what is or is not "right", here, and everyone making use of that service is obligated to those standards, regardless of their own personal feelings or values.
If prancing, as you put it, isn't a crime, then it doesn't require any special privilege to do so and there is no double standard in allowing people to do it.
Flaming/Insults/trolling is a crime, so allowing retaliatory behavior of the same caliber would most definitely be a double standard, since anyone who felt offended by anything anyone said could claim that they were justified in acting equally inappropriately.
