Why?

Why are such a large amount of this player base just rude? I can hop server to server looking for a group to play with and all i ever do is get ignored. I literally dont care what dino i play. I'm beginning to understand why the game has such a relatively small player pool. For a game that clearly incentives playing in groups you'd think more people would be happy to accept another player. Seriously considering wiping my hands of the game permanently.
