[Threshold]

Yes they are. Read the posts. Every time one of the RPI defenders gets their back in a corner, they lash out with "haha! Your mud's RP sucks." That is the dirty little sentiment that is always hidden (or sometimes not hidden) below the surface of every post. It is part of the magnanimous way they list features with explanations like "because this feature is better/more realistic" when that feature is neither better nor more realistic, but is just a preference.

And then once again, when PROVEN wrong, they lash out with personal attacks against your mud, the RP on your mud, your family, your spouse, your children, anything they can think of.

That may be the goal for some, but it definitely is not the goal of the most prolific RPI-supporting posters. If that was truly the goal, then a set of features would simply be listed - without including snarky comments about how their feature set was better or more realistic.

And they would come up with a non-vague, non-generic, non-qualitative term like RPI. They'd come up with a term like "PRP" - Prof's RP rule set or "ARP" Armageddon RP rule set or something of that nature.

There is a very clear and simple path they could take if the goal was truly listing a set of features so people who like those features could find that kind of mud. But that path never gets taken.
