Pages upon pages of text spam in say is, in fact, rude. This is just your opinion toward that kind of thing going on during RP and that is valid! However, that just means that you tolerate that form of rudeness. This is why we have different chat channels. If it were truly RP, and they were having a personal conversation in character, they would do this in /tells.
If they intend to have it be heard so maybe another RP passerby can notice and join in. That's completely understandable and this may be normal for that type of play style. However, for people who are not involved in RP this is generally rude.
Let's not treat Vedis like they are being unkind or unreasonable as if they are annoyed at someone with a mental disability. These are other players, just like you and I, who feel that their play style in general don't hold the same standards. They are not "special" and shouldn't be treated as such.
I am certainly not anti RP, but the reaction to the OP throughout the pages of this thread show the opposite of why SE should designate an official RP server. Under these circumstances with low populations it would be unwise to name an RP server due to the strong opinions against the community and you'll have a big mess on your hands with a large amount of players on one server submitting applications to move servers. More so than if they didn't officially name one. It's insensitive and it's unfair to not recognize any community and not see them as valid, but for consolidation it does make more sense to acknowledge more general and larger regional specific communities.
