*point* I know you!
And it was Lionna. Always Lionna. Until Lionna merged with.... whatever it merged with, I dunno, I stopped playing L2 years ago.
More on-topic and to the OP:
Here's the thing... RPers are, in the end, really no different from any other kind of player. We also want to level, get gear, go new places, see new things, fight big bads, and all that stuff. We might also want to fight other players. Some RPers are really *quite* good at it. There is absolutely nothing that automatically separates an RP-aficionado from a PvP-junkie... excepting that the RPer might have some sort of personal storyline as to why his/her character is taking part in that PvP battle.
For myself, I've been RPing in MMOs since EQ1 in 1999, and have been doing table-top RP games since... 1983, I think. Maybe earlier. I've seen it all, and there's really absolutely no sense or value in getting your space-suit in a twist because someone named "Boingo McFluffypantz" just ran past you on the street. Now, if someone had run by with a name that is patently offensive, using racial slurs or RL political jabs or whatever... then, sure, report them, it's against the Bioware TOS. After you report them? Go about your business and play the game. You've done your part. Someone being a jerk in General chat? Ignore them.
Me, I'm real quick with the ignore function. Blindingly quick. On the RP server I play on in EQ2 (the most populated of all their servers, incidentally, almost never dropping below "Heavy"), I may have the most people of anyone on the server on my ignore list. Most people claim to have a dozen, at most, mostly spammers and such that somehow get by the auto-ban that they tend to trigger... I've got ten times that. If people want to troll General chat, I can take all of two seconds out of my oh-so-busy schedule of bulls-eyeing womprats to ignore them, and then it is like they have utterly ceased to exist.
If people running about with silly names (though, really, a canonical name is "Salacious Crumb"... it doesn't get much sillier) somehow shatters your RP... well... I don't know what to tell you. Grow thicker skin, I guess, or get better or, really, just ignore them. The server doesn't exist as your private playground, it's a shared environment for people of all stripes. The RP tag on it lets newcomers recognise that, if they are looking for RP, they are likely to find it here.
Also, given that a lot of these character classes could be people operating under assumed names or nicknames earned through their lives... well, perhaps a name like "Thunderpants" isn't so out-of-character? Troopers named "Fiver", "Heavy", "Big Momma" or whatever have plenty of similar names from the canon regarding the Clone Wars to draw from. Smugglers operate under a variety of aliases. Maybe one is known by the moniker of "Elusive Finebooty"? RL pirates have had worse names.
Different era, to be sure, but one thing I've noticed about Star Wars is that, regardless of which era it is, it's still space ships and laser swords. The Old Republic isn't fundamentally different from the New Republic.
Overall, I think you might have a more enjoyable time of the game if you stopped worrying about what everyone else was doing and focused more on enjoying yourself. Worry about the things you can change, and forget about the things you can't.
