I don't find players friendly.

It sounds like the wrong FC honestly. Each FC's culture is different, so I would look around a bit more for a FC that suits you better. If you have 1 or 2 players you hang out with, consider asking them for social linkshell recommendations. They should be able to give you 1 or 2 recommendations and you can build from there. Eventually, you'll probably find a FC you like from those (i generally don't trust spammed recruitment messages, but they do let you network with a lot of players if you have nowhere to start).

There's several ways cliques form, but it is generally associated with a younger player age. Also, some FCs (like mine) don't spend too much time in the player chat and do most of its conversations in a VOIP. If you're not in the VOIP (which is public), you tend to miss out on a lot of conversations and socializing. It's just some food for thought on whether you're contacting them through the right channels. FCs usually advertise the chat channel if they have it and make that information available to all members.

Also, what kind of questions are you asking and what kind of answers do you get back? It's odd that a FC will only give sarcastic answers to an honest question, and it does suggest some deep-seated problems. I don't know what happened between you and the FC, but I will say if they're antagonistic towards you, you should probably leave. It's not good for anybody to be around people that hate each other.
