<Snipped quote by ArenaSnow>
Interesting. I tend to distance myself as much as I can from my characters, and distance other people as much from their characters as I can. If I find someone annoying, I can usually still RP with them unless all their characters are shameless self-inserts.
I find that, while I can distance both myself, and others from their characters, if I have an issue with a person: They can go fuck themselves. I don't dislike someone arbitrarily, there's pretty much always a reason.
As to a previous statement you made about being here to RP and not make friends: That is a very inaccurate assumption. Most people that I've met do actually want to make friends through RP. As was mentioned earlier, RP is a very social thing. You need to be able to interact with, and respect the partners, or group that you have. In most cases, people will treat you the way you treat them, and because this is the internet if you're a jackass, you're likely not to make many permanent RP partners, because people are probably not going to deal with your bullshit.
As a note: I'd like to apologize if this came off as rude, or harsh, just stating my opinion based on my own experiences with this site.
Moving on to your actual question: There are people who will write with you in a very professional manner, and won't go out of their way to talk to you OOC unless it's to talk about plot-related things. They won't judge you based on your attitude, simply on your writing level. However, it should be noted that most adults on this site won't RP with you in terms of Romance due to legal issues involving contacting a minor in that way. It's just not a good idea, overall, to be honest.
Most people would likely give the advice to start in Free because that's how they learned, and just because you're a good academic writer doesn't mean you understand Roleplay, or Roleplay etiquette. You can write, that doesn't mean you can RP. There're rules, and guidelines that people want newbies to understand. A lot of newbies to play-by-post learn these the hard way by being yelled at by their "seniors." I have yet to see that [recently] on the Guild, however.
So, they may not be trying to insult you; they may just want to help you learn in the only way they know how. Unless, of course you've already displayed some sort of decorum and understanding of roleplaying etiquette as a whole, in which case: I don't know why anyone would say that to you.
The emotion thing doesn't make any sense to me, because RP shouldn't stress you out. It should be fun, and a break from reality. If you're getting stressed out by an RP, you're taking it too seriously.
